Tri(pentan-2-yl) borate CAS 40589-08-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tri(pentan-2-yl) borate.

Tri(pentan-2-yl) borate (CAS 40589-08-0), molecular formula C15H33BO3 and molecular weight 272.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tri(pentan-2-yl) borate (C15H33BO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

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.

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.
