Chemical Structure

2-Propenoic acid, 2-methyl-, polymer with 2-propenoic acid, sodium salt CAS 28205-96-1 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 2-propenoic acid, sodium salt.

CATO supplies 2-Propenoic acid, 2-methyl-, polymer with 2-propenoic acid, sodium salt (CAS 28205-96-1), a certified reference material (molecular formula C4H6O2C3H3O2Na, MW 180.13 g/mol) for analytical method development and quality control.

Structurally, 2-Propenoic acid, 2-methyl-, polymer with 2-propenoic acid, sodium salt (C4H6O2C3H3O2Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 180.13 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 2-Propenoic acid, 2-methyl-, polymer with 2-propenoic acid, sodium salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
