Chemical Structure

2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate) CAS 66057-42-9 chemical structure

Description

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-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate).

2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate) (CAS 66057-42-9) is a high-purity analytical reference standard with the molecular formula C7H12O3C8H14O2C4H6O2 and a molecular weight of 372.46 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-2-propenoate) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.46 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
