Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-2-chlorobenzoic Acid Sodium salt (CAS 1938142-12-1), molecular formula C7H3BrClO2Na and molecular weight 257.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H3BrClO2Na, 5-Bromo-2-chlorobenzoic Acid Sodium salt contains a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 5-Bromo-2-chlorobenzoic 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.
