Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2-Methyl-3,5-dinitrophenyl)boronic acid.
(2-Methyl-3,5-dinitrophenyl)boronic acid (CAS 24341-76-2), molecular formula C7H7BN2O6 and molecular weight 225.95 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Methyl-3,5-dinitrophenyl)boronic acid (C7H7BN2O6) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, 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), (2-Methyl-3,5-dinitrophenyl)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.
