Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3,5-Trimethylbenzo[c][1,2]oxaborol-1(3H)-ol.
3,3,5-Trimethylbenzo[c][1,2]oxaborol-1(3H)-ol (CAS 1393477-33-2) is a high-purity analytical reference standard with the molecular formula C10H13BO2 and a molecular weight of 176.02 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3,3,5-Trimethylbenzo[c][1,2]oxaborol-1(3H)-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3,3,5-Trimethylbenzo[c][1,2]oxaborol-1(3H)-ol 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.
