Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene and 1,2-propanediol mono(2-methyl-2-propenoate).
2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene and 1,2-propanediol mono(2-methyl-2-propenoate) (CAS 9045-82-3), molecular formula C7H12O3C7H12O2C8H8C4H6O2 and molecular weight 462.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylbenzene and 1,2-propanediol mono(2-methyl-2-propenoate) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
