Chemical Structure

2-(3-Methylisoxazol-5-yl)hydrazinecarboxamide CAS 81259-50-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Methylisoxazol-5-yl)hydrazinecarboxamide.

CATO supplies 2-(3-Methylisoxazol-5-yl)hydrazinecarboxamide (CAS 81259-50-9), a certified reference material (molecular formula C5H8N4O2, MW 156.14 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 2-(3-Methylisoxazol-5-yl)hydrazinecarboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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-(3-Methylisoxazol-5-yl)hydrazinecarboxamide 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.
