Chemical Structure
Description
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.
(3-Chloro-2-(trimethylsilyl)phenyl)boronic acid (CAS 1257792-93-0) is a high-purity analytical reference standard with the molecular formula C9H14BClO2Si and a molecular weight of 228.56 g/mol.
(3-Chloro-2-(trimethylsilyl)phenyl)boronic acid (C9H14BClO2Si) 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.
CATO manufactures (3-Chloro-2-(trimethylsilyl)phenyl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
