2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 1-ethyl hydrogen (2Z)-2-butenedioate CAS 68318-23-0 chemical structure

Description

As a certified reference material (CRM), 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 1-ethyl hydrogen (2Z)-2-butenedioate 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.

2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 1-ethyl hydrogen (2Z)-2-butenedioate (CAS 68318-23-0), molecular formula C12H20O4C6H8O4C4H6O2 and molecular weight 458.50 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Butenedioic acid (2Z)-, 1,4-dibutyl ester, polymer with ethenyl acetate and 1-ethyl hydrogen (2Z)-2-butenedioate (C12H20O4C6H8O4C4H6O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
