Chemical Structure

(S)-2-ethyl-2-methylpentanoic acid CAS 159225-52-2 chemical structure

Description

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.

(S)-2-ethyl-2-methylpentanoic acid (CAS 159225-52-2) is a high-purity analytical reference standard with the molecular formula C8H16O2 and a molecular weight of 144.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-2-ethyl-2-methylpentanoic acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
