Chemical Structure

Salicylaldehyde hydrazone CAS 3291-00-7 chemical structure

Description

Salicylaldehyde hydrazone (CAS 3291-00-7), molecular formula C7H8N2O and molecular weight 136.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Salicylaldehyde hydrazone (C7H8N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Salicylaldehyde hydrazone 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.
