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.
