4'-Chloro-3-nitro-[1,1'-biphenyl]-4-amine CAS 31433-98-4

Description

The occurrence of 4'-Chloro-3-nitro-[1,1'-biphenyl]-4-amine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4'-Chloro-3-nitro-[1,1'-biphenyl]-4-amine (CAS 31433-98-4), a certified reference material (molecular formula C12H9ClN2O2, MW 248.67 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, 4'-Chloro-3-nitro-[1,1'-biphenyl]-4-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.67 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.

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 4'-Chloro-3-nitro-[1,1'-biphenyl]-4-amine 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.
