Compared with other compounds in its class, the molecular weight of 166.01 g/mol gives 4-Methylthieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Methylthieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (CAS 58157-75-8), molecular formula C6H7BN2OS and molecular weight 166.01 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methylthieno[3,2-d][1,2,3]diazaborinin-1(2H)-ol (C6H7BN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. 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 166.01 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
