Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium 3,6-dichloro-2-oxidobenzoate.
Potassium 3,6-dichloro-2-oxidobenzoate (CAS 68938-80-7), molecular formula C7H2Cl2O3K and molecular weight 244.09 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium 3,6-dichloro-2-oxidobenzoate (C7H2Cl2O3K) contains a salt form, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Potassium 3,6-dichloro-2-oxidobenzoate 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.
