(S)-3-Methylbenzo[c][1,2]oxaborol-1(3H)-ol CAS 1388265-61-9

Description

Compared with other compounds in its class, the molecular weight of 147.97 g/mol gives (S)-3-Methylbenzo[c][1,2]oxaborol-1(3H)-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-3-Methylbenzo[c][1,2]oxaborol-1(3H)-ol (CAS 1388265-61-9), a certified reference material (molecular formula C8H9BO2, MW 147.97 g/mol) for analytical method development and quality control.

Structurally, (S)-3-Methylbenzo[c][1,2]oxaborol-1(3H)-ol (C8H9BO2) contains a carboxylic acid group, 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 147.97 g/mol, it falls into the low-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.
