Chemical Structure
Description
The occurrence of 3-Amino-2,5-dichlorobenzoic Acid Sodium Salt is closely related to a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Amino-2,5-dichlorobenzoic Acid Sodium Salt (CAS 1954-81-0), a certified reference material (molecular formula C7H4Cl2NO2Na, MW 228.00 g/mol) for analytical method development and quality control.
3-Amino-2,5-dichlorobenzoic Acid Sodium Salt (C7H4Cl2NO2Na) contains a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Amino-2,5-dichlorobenzoic Acid Sodium Salt 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.
