Description

3-NITRO-4-CHLOROBENZOYL CHLORIDE 38818-50-7 4-Chloro-3-nitrobenzoyl chloride AKOS B022432 ART-CHEM-BB B022432 AS00023 ATTERCOP-CHM AT106925 LABOTEST-BB LT03408094 OTAVA-BB 1376728 TIMTEC-BB SBB006725 (CAS 38818-50-7), molecular formula C7H3Cl2NO3 and molecular weight 220.01 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-NITRO-4-CHLOROBENZOYL CHLORIDE 38818-50-7 4-Chloro-3-nitrobenzoyl chloride AKOS B022432 ART-CHEM-BB B022432 AS00023 ATTERCOP-CHM AT106925 LABOTEST-BB LT03408094 OTAVA-BB 1376728 TIMTEC-BB SBB006725 (C7H3Cl2NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
