Chemical Structure

2-benzyl-2,3-dimethylbutanoic acid CAS 908104-80-3 chemical structure

Description

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 supplies 2-benzyl-2,3-dimethylbutanoic acid (CAS 908104-80-3), a certified reference material (molecular formula C13H18O2, MW 206.28 g/mol) for analytical method development and quality control.

The molecular framework of 2-benzyl-2,3-dimethylbutanoic acid (C13H18O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
