Chemical Structure
Description
Methyl (E)-2-(3,5-di-tert-butyl-4-hydroxybenzylidene)hydrazine-1-carboxylate (CAS 860650-67-5), molecular formula C17H26N2O3 and molecular weight 306.40 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl (E)-2-(3,5-di-tert-butyl-4-hydroxybenzylidene)hydrazine-1-carboxylate (C17H26N2O3) 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 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 Methyl (E)-2-(3,5-di-tert-butyl-4-hydroxybenzylidene)hydrazine-1-carboxylate 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.
