Chemical Structure
Description
5-(Butylthio)pyridine-3-boronic acid (CAS 2096339-87-4), molecular formula C9H14BNO2S and molecular weight 211.09 g/mol, is a CATO reference standard with documented purity and traceability.
5-(Butylthio)pyridine-3-boronic acid (C9H14BNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 5-(Butylthio)pyridine-3-boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
