(E)-4-((4-Aminophenyl)Diazenyl)-2-chlorophenol CAS 669092-47-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-((4-Aminophenyl)Diazenyl)-2-chlorophenol.

CATO supplies (E)-4-((4-Aminophenyl)Diazenyl)-2-chlorophenol (CAS 669092-47-1), a certified reference material (molecular formula C12H10ClN3O, MW 247.68 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, chlorine substitution, (E)-4-((4-Aminophenyl)Diazenyl)-2-chlorophenol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 247.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
