2-chloro-5-fluoro-4-nitro-aniline CAS 517920-71-7

Description

The occurrence of 2-chloro-5-fluoro-4-nitro-aniline is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-chloro-5-fluoro-4-nitro-aniline (CAS 517920-71-7), molecular formula C6H10ClFN2O2 and molecular weight 196.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-chloro-5-fluoro-4-nitro-aniline is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.61 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 2-chloro-5-fluoro-4-nitro-aniline 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.
