Chemical Structure
Description
The molecular framework of 2-(2-Isopropyl-4-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H25BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
2-(2-Isopropyl-4-methylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 2839742-54-8), molecular formula C16H25BO2 and molecular weight 260.18 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
