Chemical Structure
Description
The occurrence of 5-Chlorobenzo[c][1,2]oxaborol-1(3H)-ol is closely related to 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.
5-Chlorobenzo[c][1,2]oxaborol-1(3H)-ol (CAS 174672-06-1), molecular formula C7H6BClO2 and molecular weight 168.39 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chlorobenzo[c][1,2]oxaborol-1(3H)-ol (C7H6BClO2) contains 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
