2-thienylboronic acid 2-thiophene boric acid 2-thiophene boronic acid 2-thiopheneboronic acid 2-thiophenylboric acid 6165-68-0 Thiophene-2-boronic acid thiophen-2-ylboranediol thiophen-2-ylboronic acid thiophene 2-boronic acid thiophene2-boronic acid thiophenyl 2-boronic acid (CAS 6165-68-0), molecular formula C4H9BO2S and molecular weight 131.99 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H9BO2S, 2-thienylboronic acid 2-thiophene boric acid 2-thiophene boronic acid 2-thiopheneboronic acid 2-thiophenylboric acid 6165-68-0 Thiophene-2-boronic acid thiophen-2-ylboranediol thiophen-2-ylboronic acid thiophene 2-boronic acid thiophene2-boronic acid thiophenyl 2-boronic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 131.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
