2-(Methylthio)thiophene-3-boronic acid CAS 1451392-35-0

Description

Compared with other compounds in its class, the molecular weight of 174.05 g/mol gives 2-(Methylthio)thiophene-3-boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Methylthio)thiophene-3-boronic acid (CAS 1451392-35-0), molecular formula C5H7BO2S2 and molecular weight 174.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(Methylthio)thiophene-3-boronic acid (C5H7BO2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
