Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,6-Dimethoxy-3-methylsulfanylpyridine-5-boronic acid (CAS 2121512-34-1) is a high-purity analytical reference standard with the molecular formula C8H12BNO4S and a molecular weight of 229.06 g/mol.
Based on its molecular formula C8H12BNO4S, 2,6-Dimethoxy-3-methylsulfanylpyridine-5-boronic acid contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
