Description

CATO manufactures 4,4,5,5-Tetramethyl-2-(4-phenylbut-1-yn-1-yl)-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.

4,4,5,5-Tetramethyl-2-(4-phenylbut-1-yn-1-yl)-1,3,2-dioxaborolane (CAS 159087-44-2) is a high-purity analytical reference standard with the molecular formula C16H21BO2 and a molecular weight of 256.15 g/mol.

4,4,5,5-Tetramethyl-2-(4-phenylbut-1-yn-1-yl)-1,3,2-dioxaborolane (C16H21BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
