Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-phenylthiazol-4-yl)boronate (CAS 2223041-81-2), molecular formula C15H20BNO3S and molecular weight 305.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-phenylthiazol-4-yl)boronate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.20 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).
As a certified reference material (CRM), 3-Hydroxy-2,3-dimethylbutan-2-yl hydrogen (5-phenylthiazol-4-yl)boronate 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.
