Chemical Structure

5'-Formyl-2,2'-bithiophene-5-boronic Acid(contains varying amounts of Anhydride) CAS 1369328-62-0 chemical structure

Description

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.

5'-Formyl-2,2'-bithiophene-5-boronic Acid(contains varying amounts of Anhydride) (CAS 1369328-62-0), molecular formula C9H7BO3S2 and molecular weight 238.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H7BO3S2, 5'-Formyl-2,2'-bithiophene-5-boronic Acid(contains varying amounts of Anhydride) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
