a For all Listings above containing the word “Compounds,” the following applies: Unless otherwise specified, these listings are defined as including any unique chemical substance that contains the named chemical (i.e., antimony, arsenic) as part of that chemical's infrastructure.

b Isomer means all structural arrangements for the same number of atoms of each element and does not mean salts, esters, or derivatives.

c CAS No. = Chemical Abstract Service number.

d Includes mono- and di- ethers of ethylene glycol, diethylene glycol, and triethylene glycol R-(OCH2 CH2n-OR where:

n = 1, 2, or 3;

R = alkyl or aryl groups; and

R″ = R, H or groups which, when removed, yield glycol ethers with the structure:

R-(OCH2 CH2n-OH

Polymers are excluded from the glycol category.
