Chemical Structure
Description
The occurrence of 2-[3-Chloro-4-(methanesulfonylmethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-[3-Chloro-4-(methanesulfonylmethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2253750-91-1), a certified reference material (molecular formula C14H20BClO4S, MW 330.64 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-[3-Chloro-4-(methanesulfonylmethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 2-[3-Chloro-4-(methanesulfonylmethyl)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
