Chemical Structure

2,5-Dimethyl-3-hexanone CAS 1888-57-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dimethyl-3-hexanone.

2,5-Dimethyl-3-hexanone (CAS 1888-57-9) is a high-purity analytical reference standard with the molecular formula C8H16O and a molecular weight of 128.21 g/mol.

Owing to a hydroxyl group, an ether linkage, 2,5-Dimethyl-3-hexanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.21 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.

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.
