Chemical Structure

2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylmethylbenzene and methyl 2-methyl-2-propenoate CAS 56602-76-7 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-propenoate, ethenylmethylbenzene and methyl 2-methyl-2-propenoate.

CATO supplies 2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylmethylbenzene and methyl 2-methyl-2-propenoate (CAS 56602-76-7), a certified reference material (molecular formula C7H12O2C9H10C5H8O2C4H6O2, MW 432.56 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 2-Propenoic acid, 2-methyl-, polymer with butyl 2-propenoate, ethenylmethylbenzene and methyl 2-methyl-2-propenoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
