Test material
- Reference substance name:
- Methacrylic acid, monoester with propane-1,2-diol
- EC Number:
- 248-666-3
- EC Name:
- Methacrylic acid, monoester with propane-1,2-diol
- Cas Number:
- 27813-02-1
- Molecular formula:
- C7H12O3
- IUPAC Name:
- 1-hydroxypropan-2-yl 2-methylprop-2-enoate; 2-hydroxypropyl 2-methylprop-2-enoate
- Test material form:
- liquid
- Details on test material:
- The chemical 2-propenoic acid, 2-methyl-, monoester with 1,2-propanediol (CAS No. 27813-02-1) consists of two isomers. This occurs due to the method of industrial production, which is usually either the reaction between methacrylic acid and propylene oxide, or methacrylic acid esterification of 1,2-propanediol. The predominant isomer is the secondary alcohol 2-propenoic acid, 2-methyl, 2-hydroxypropyl ester, which is assigned the CAS No. 923-26-2, and the isomer 2-propenoic acid, 2-methyl, 2-hydroxy- 1-methylethyl ester, the other chemical in this group, for which CAS 4664-49-7 is assigned. The purification of the two isomers requires extensive effort and it is supposed no such effort has been taken during data collection otherwise noted. Therefore toxicity information for both CAS No. 923-26-2 and CAS No. 27813-02-1 is considered to be applicable to both chemicals..
