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-((3,4-Diphenylisoxazol-5-yl)(phenyl)methylene)hydrazinecarboxamide.
2-((3,4-Diphenylisoxazol-5-yl)(phenyl)methylene)hydrazinecarboxamide (CAS 62224-84-4) is a high-purity analytical reference standard with the molecular formula C23H18N4O2 and a molecular weight of 382.41 g/mol.
The molecular framework of 2-((3,4-Diphenylisoxazol-5-yl)(phenyl)methylene)hydrazinecarboxamide (C23H18N4O2) is characterized by a steroid 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. 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).
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-((3,4-Diphenylisoxazol-5-yl)(phenyl)methylene)hydrazinecarboxamide 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.
