Preface
This glossary is intended to facilitate communication within the Food and Drug Administration
(FDA) on the subject of pesticide residues in foods and feeds. It serves as the source of names
chosen for use in all agency documents and internal communications.
Chemicals are listed, alphabetically by preferred name, in the body of the glossary. The preferred
name is printed in bold-face type, as is the CAS Registry number assigned by Chemical Abstracts
Service (not available for some entries). Alternate names are identified by type of name. An index
provides a cross-reference to the preferred name for each alternate name.
Use the index to find the name used for any chemical in the body of the Glossary. Then find the
main entry for that chemical to obtain additional alternate names and other information.
The glossary includes parent pesticides with U.S. tolerances on foods or feeds (40 CFR 180, 185,
186), or with temporary or pending tolerances. It also includes pesticides which previously had
U.S. tolerances, those known or suspected of being used on foods in other countries, and those
for which common names have recently been approved by ANSI and/or ISO. Absence of a
chemical which meets these criteria is either inadvertent or results from failure to locate sufficient
information for entry.
The glossary contains only limited entries for pesticide components, metabolites, breakdown
products, or impurities; see page iii for directions on how to obtain information about additional
chemicals in these categories. The glossary also contains only selected industrial chemicals,
usually those known to be detected during analysis of foods for pesticide residues.
Preferred names were chosen according to the following sequence:
• ANSI (American National Standards Institute) approved common name
• ISO (International Standards Organization) approved common name
• other common names
• acronym or other term which has gained general acceptance
• chemical name if sufficiently short
• trade name
In some cases where no ANSI or ISO name exists, the preferred name was chosen from among
several possibilities because it has already been used within the agency for a period of time.
Other Information
The following additional information is included, if available, for each chemical:
Use: most common use of pesticide; left blank for components, metabolites, etc.
Category: parent, metabolite, etc.
Molecular Formula: Numbers are not subscripted.
LMS Code: as used by FDA to report analytical results.
Tolerances: references to 40 CFR 180 and 40 CFR 185-86; also notes temporary, pending, or
revoked tolerances and indicates use in other countries (“foreign use”).

Naming Conventions
Names proposed as ANSI common names, but not yet approved, are not normally used. When
exceptions are made, the notation “(prop)” is included with the name.
Names proposed as ISO common names and considered acceptable by mail ballot are used, even
when they have not yet appeared in a Draft Addendum to ISO document 1750, Pesticides and
other agrochemicals—Common names.
Names approved as ISO common names but designated as unacceptable in the U.S. are listed in
the Glossary but are not used as preferred names, even when no ANSI name exists.
Certain “other” names are entered for explanatory purposes, e.g., “captan metabolite”, “chlordane
component”. In some cases, these names will occur once for each of the chemicals to which they
refer.
Chemical names which follow the nomenclature rules of the Chemical Abstracts Service’s 9th
Collective Index (9CI) are used for all entries for which such a name exists. In certain cases, other
chemical names are also included; these are labelled as “other” names.
Chemical names are entered in direct order. Exceptions to this include the following
stereochemical descriptors, which are printed after the name following a comma:
• cis- and trans-
• alpha, beta, etc., (sometimes abbreviated to A and B for space considerations)
• o-, m-, and p-
• (±)-
• (E)- and (Z)-
• endo- and exo-
Note that alpha and beta are also used as locants in some names; in these cases, the terms are
not abbreviated and are not placed at the end of the name.
Names are alphabetized by computer according to the following sequence:
space ! + # $ % & + ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ? @
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ]
An “=” is used to create an artifical line break in a long chemical name; no space or hyphen
occurs in the actual name at that point.

Database Files
As previously noted, only limited entries exist in the Glossary for pesticide components,
metabolites, breakdown products, and impurities. More complete listings are available in files
FDA makes available in a format suitable for creating databases. For example, this Glossary
contains entries for 1045 chemicals (with 5910 alternate names); theMay 2005 version of the
database files contains records for 1603 chemicals.
Also available in the database files is other information useful to the laboratory or administrator
dealing with pesticides. Particular emphasis is given to data on the behavior of chemicals in FDA
multiresidue analytical methods published in Pesticide Analytical Manual Vol. I (PAM I).
FDA provides the database files in electronic format on the Internet for access via World Wide
Web. Basic information about the files, how to obtain them, and how to use them follows.
Explanatory files that accompany the data files provide more details.
What the Files Are
The following two sets of files are available, each in compressed .exe form. These can be
decompressed on Windows systems by double-clicking, and on Macintosh systems by use of
Stuffit Expander; access to this decompression software is provided.
Pestrak
Decompresses to five files, one of which, ExplnPtk.txt, explains the other four.
Each of the others is designed for importing into database or spreadsheet
software. See page iv for the names of the files and categories of information in
each file. Each of the four can be used as a separate database, or the four can
be linked using relational database software.
PESTDATA
Decompresses to two files, one of which, ExplnPD.txt, explains the other,
PESTDATA.txt. The latter, designed for importing into database or spreadsheet
software, contains data on the behavior of chemicals through PAM I methods.
See page iv for the categories of information in this file, which is used by FDA to
create PAM I Appendix I.
How to Get the Files via WWW
Go to the World Wide Web site at: http://www.cfsan.fda.gov/list.html. Follow the links for
Pesticides and Chemical Contaminants, then Pesticide Analytical Behavior Data (under the
heading Pesticides: Technical Information). Or go directly to the page: http://www.cfsan.fda.gov/
~frf/pestdata.html. Read descriptions of the available files and follow the links to download them.
How to Use the Files
Each file listed on page iv is a text (ASCII) file. Read the “Expln” files with word processing
software using a monospaced (nonproportional) font. Import the remaining data files into software
designed to create a data base. (Files are tab-delimited, a format recognized by most database and
spreadsheet software.) Use the databases to sort data, perform searches, or prepare reports as
desired.
Files will be updated annually.
Compare dates to see whether you have the latest versions.
