2,2′-Bis(salicylideneamino)azobenzene CAS 1258669-34-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2′-Bis(salicylideneamino)azobenzene.

CATO supplies 2,2′-Bis(salicylideneamino)azobenzene (CAS 1258669-34-9), a certified reference material (molecular formula C26H20N4O2, MW 420.46 g/mol) for analytical method development and quality control.

Structurally, 2,2′-Bis(salicylideneamino)azobenzene (C26H20N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 420.46 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.

As a certified reference material (CRM), 2,2′-Bis(salicylideneamino)azobenzene 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.
