Chemical Structure

2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with ethenyl acetate and 2-propenoic acid CAS 56280-96-7 chemical structure

Description

The occurrence of 2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with ethenyl acetate and 2-propenoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with ethenyl acetate and 2-propenoic acid (CAS 56280-96-7), molecular formula C5H6O4C4H6O2C3H4O2 and molecular weight 288.25 g/mol, is a CATO reference standard with documented purity and traceability.

2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with ethenyl acetate and 2-propenoic acid (C5H6O4C4H6O2C3H4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with ethenyl acetate and 2-propenoic acid 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.
