Description
CATO manufactures 4-Hydroxy-3-nitrobenzoyl chloride 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.
CATO supplies 4-Hydroxy-3-nitrobenzoyl chloride (CAS 85136-67-0), a certified reference material (molecular formula C7H4ClNO4, MW 201.56 g/mol) for analytical method development and quality control.
The molecular framework of 4-Hydroxy-3-nitrobenzoyl chloride (C7H4ClNO4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
