Technical-grade endosulfan contains at least 94% of two pure isomers, a- and P-endosulfan (Maier-Bode 1968 NRCC 1975). The a- and p-isomers of endosulfan are present in the ratio of 7 3, respectively. Technical-grade endosulfan may also contain up to 2% endosulfan alcohol and 1% endosulfan ether. Endosulfan sulfate is a reaction product found in technical endosulfan it is also found in the environment due to photolysis and in organisms as a result of oxidation by biotransformation (EPA 1979 Coleman and Dolinger 1982). The chemical formula, structure, synonyms, and identification numbers for endosulfan, a-endosulfan, p-endosulfan, and endosulfan sulfate are listed in Tables 3-1, 3-2, 3-3, and 3-4, respectively. 

The chemical formula, structure, synonyms, and identification numbers for trichloroethylene are listed in Table 3-1. 

Material Safety Data Sheets (MSDS). The MSDS CD-ROM is a useful resource that contains over 33,000 MSDS on chemicals submitted to the Occupational Safety and Health Administration (OSHA) by chemical manufacturers. This resource contains complete Material Safety Data Sheet (MSDS) information as well as other important information such as the chemical formula, structure, physical properties, synonyms, registry number, and safety information.

Hydrocarbons are classified by whether their carbon structure includes rings, multiple bonds, or branches. Classification of hydrocarbon structural families is shown here with the chemical formula. Structures are shown as Kekule (also called line-bond) and skeletal structures.

Chemical composition of herbs is always a complex subject. A medicinal herb can be compared with a chemical factory due to presence of number of chemical constituents. The literature on this aspect is scattered and what is required today is a textbook covering all aspects including chemical formulas, structures and standards applicable to isolated constituents with special reference to biological activity. This book is an attempt in that direction.
