C15H28Cl4COOCH3 and C15H27Cl5COOCH3 (primary isomers based on 35-40% Cl by weight)
IUPAC Name:
Methyl hexadecanoate, chloro
Constituent 3
Reference substance name:
Methyl dodecanoate, chloro
Molecular formula:
C19H31Cl5COOCH3 and C19H30Cl6COOCH3 (primary isomers based on 35-40% Cl by weight)
IUPAC Name:
Methyl dodecanoate, chloro
additive 1
Chemical structure
Reference substance name:
Soybean oil, epoxidized
EC Number:
232-391-0
EC Name:
Soybean oil, epoxidized
Cas Number:
8013-07-8
Molecular formula:
C57H98O12
IUPAC Name:
Epoxidized Soybean Oil
Test material form:
liquid
Details on test material:
A complex combination of chlorinated fatty acid mtethyl esters that are predominantly C18 (~ 70 – 85%) and C16 (~ 15 - 30%) in length. The chlorination levels by weight are between 35-40%. The chlorination process is largely random, though chlorination will occur first by direct addition at unsaturated sites in the unsaturated methyl esters present in the starting material.
