Chemical Structure

3,7-Dimethyl-1-octanolacetate CAS 20780-49-8 chemical structure

Description

CATO supplies 3,7-Dimethyl-1-octanolacetate (CAS 20780-49-8), a certified reference material (molecular formula C12H24O2, MW 200.32 g/mol) for analytical method development and quality control.

The molecular framework of 3,7-Dimethyl-1-octanolacetate (C12H24O2) 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.
