Chemical Structure

4-(Phenyldiazenyl)benzamide CAS 29530-53-8 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies 4-(Phenyldiazenyl)benzamide (CAS 29530-53-8), a certified reference material (molecular formula C13H11N3O, MW 225.25 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-(Phenyldiazenyl)benzamide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 225.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
