(E)-N'-benzylidene-5-methylisoxazole-3-carbohydrazide CAS 91397-11-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-N'-benzylidene-5-methylisoxazole-3-carbohydrazide.

(E)-N'-benzylidene-5-methylisoxazole-3-carbohydrazide (CAS 91397-11-4), molecular formula C12H11N3O2 and molecular weight 229.23 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-N'-benzylidene-5-methylisoxazole-3-carbohydrazide (C12H11N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 (E)-N'-benzylidene-5-methylisoxazole-3-carbohydrazide 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.
