Chemical Structure
Description
The occurrence of 4,4,5,5-Tetramethyl-2-(3-(methylsulfinyl)phenyl)-1,3,2-dioxaborolane is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4,5,5-Tetramethyl-2-(3-(methylsulfinyl)phenyl)-1,3,2-dioxaborolane (CAS 1416367-04-8), molecular formula C13H19BO3S and molecular weight 266.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4,4,5,5-Tetramethyl-2-(3-(methylsulfinyl)phenyl)-1,3,2-dioxaborolane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4,4,5,5-Tetramethyl-2-(3-(methylsulfinyl)phenyl)-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.
