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-Butenedioic acid (2Z)-, polymer with (2Z)-4-amino-4-oxo-2-butenoic acid and ethenylbenzene, ammonium salt (CAS 68171-59-5), molecular formula C4H4O4C4H4NO3C8H8H4N and molecular weight 352.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Butenedioic acid (2Z)-, polymer with (2Z)-4-amino-4-oxo-2-butenoic acid and ethenylbenzene, ammonium salt (C4H4O4C4H4NO3C8H8H4N) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO manufactures 2-Butenedioic acid (2Z)-, polymer with (2Z)-4-amino-4-oxo-2-butenoic acid and ethenylbenzene, ammonium salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
