Chemical Structure
Description
CATO supplies Dibenzo[b,d]thiophene-2,8-diyldiboronic acid (CAS 761405-37-2), a certified reference material (molecular formula C12H10B2O4S, MW 271.89 g/mol) for analytical method development and quality control.
Structurally, Dibenzo[b,d]thiophene-2,8-diyldiboronic acid (C12H10B2O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 271.89 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
