Description
As a certified reference material (CRM), 2-(Propylsulfonyl)thieno[3,2-d][1,2,3]diazaborinin-1(2H)-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.
2-(Propylsulfonyl)thieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (CAS 67398-10-1), molecular formula C8H11BN2O3S2 and molecular weight 258.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Propylsulfonyl)thieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (C8H11BN2O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 258.13 g/mol, it falls into the medium-molecular-weight range. 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.
