Chemical Structure
Description
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.
4-[(1,1-Dioxidothiomorpholino)methyl]phenylboronic Acid Pinacol Ester (CAS 1092563-25-1), molecular formula C17H26BNO4S and molecular weight 351.27 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(1,1-Dioxidothiomorpholino)methyl]phenylboronic Acid Pinacol Ester (C17H26BNO4S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
