Chemical Structure
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.
(E)-N-(4-(2-(1-(3-aminophenyl)ethylidene)hydrazine-1-carbonyl)phenyl)acetamide (CAS 349638-38-6) is a high-purity analytical reference standard with the molecular formula C17H18N4O2 and a molecular weight of 310.35 g/mol.
The molecular framework of (E)-N-(4-(2-(1-(3-aminophenyl)ethylidene)hydrazine-1-carbonyl)phenyl)acetamide (C17H18N4O2) 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. 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 (E)-N-(4-(2-(1-(3-aminophenyl)ethylidene)hydrazine-1-carbonyl)phenyl)acetamide 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.
