Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dihydro-2,1-benzoxaborole-1,5-diol.
1,3-Dihydro-2,1-benzoxaborole-1,5-diol (CAS 1187190-70-0), molecular formula C7H7BO3 and molecular weight 149.94 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3-Dihydro-2,1-benzoxaborole-1,5-diol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,3-Dihydro-2,1-benzoxaborole-1,5-diol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
