Chemical Structure
Description
As a certified reference material (CRM), 2,6-Dichloro-3-methylphenylboronic 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.
CATO supplies 2,6-Dichloro-3-methylphenylboronic Acid (CAS 851756-54-2), a certified reference material (molecular formula C7H7BCl2O2, MW 204.85 g/mol) for analytical method development and quality control.
2,6-Dichloro-3-methylphenylboronic Acid (C7H7BCl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
