Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with 1,3-butadiene and ethenylbenzene.
2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with 1,3-butadiene and ethenylbenzene (CAS 27322-65-2) is a high-purity analytical reference standard with the molecular formula C5H6O4C8H8C4H6 and a molecular weight of 288.34 g/mol.
The molecular framework of 2-Butenedioic acid (2Z)-, 1-methyl ester, polymer with 1,3-butadiene and ethenylbenzene (C5H6O4C8H8C4H6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 1,3-butadiene and ethenylbenzene 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.
