Chemical Structure
Description
The occurrence of 2-Butenedioic acid (2Z)-, ammonium salt is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Butenedioic acid (2Z)-, ammonium salt (CAS 39444-67-2), a certified reference material (molecular formula C4H2O4H4N, MW 132.09 g/mol) for analytical method development and quality control.
2-Butenedioic acid (2Z)-, ammonium salt (C4H2O4H4N) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 2-Butenedioic acid (2Z)-, 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.
