2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene, 2-methylpropyl 2-methyl-2-propenoate, 2-methylpropyl 2-propenoate and 2-oxiranylmethyl 2-methyl-2-propenoate CAS 68155-84-0

Description

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.

2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene, 2-methylpropyl 2-methyl-2-propenoate, 2-methylpropyl 2-propenoate and 2-oxiranylmethyl 2-methyl-2-propenoate (CAS 68155-84-0) is a high-purity analytical reference standard with the molecular formula C8H14O2C7H10O3C7H12O2C8H8C5H8O2 and a molecular weight of 616.79 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene, 2-methylpropyl 2-methyl-2-propenoate, 2-methylpropyl 2-propenoate and 2-oxiranylmethyl 2-methyl-2-propenoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 616.79 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).

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.
