Chemical Structure

2-Ethyl-5-methyl-4-phenyl-1,3,2-dioxaborinane CAS 74646-03-0 chemical structure

Description

The molecular framework of 2-Ethyl-5-methyl-4-phenyl-1,3,2-dioxaborinane (C12H17BO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-Ethyl-5-methyl-4-phenyl-1,3,2-dioxaborinane (CAS 74646-03-0), molecular formula C12H17BO2 and molecular weight 204.07 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.
