Chemical Structure
Description
The occurrence of 5-Hydroxy-2-nitrobenzoic Acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Hydroxy-2-nitrobenzoic Acid (CAS 610-37-7), a certified reference material (molecular formula C7H5NO5, MW 183.12 g/mol) for analytical method development and quality control.
5-Hydroxy-2-nitrobenzoic Acid (C7H5NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 5-Hydroxy-2-nitrobenzoic Acid 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.
