Thieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol CAS 4347-35-7

Description

The molecular framework of Thieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (C5H5BN2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Thieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (CAS 4347-35-7) is a high-purity analytical reference standard with the molecular formula C5H5BN2OS and a molecular weight of 151.98 g/mol.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 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.
