aFor 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.
bIsomer means all structural arrangements for the same number of atoms of each element and does not mean salts, esters, or derivatives.
cCAS No. = Chemical Abstract Service number.
dIncludes 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.
