Chemical Structure

12-Methyl-8-oxotridecanoic acid CAS 32746-64-8 chemical structure

Description

CATO supplies 12-Methyl-8-oxotridecanoic acid (CAS 32746-64-8), a certified reference material (molecular formula C14H26O3, MW 242.35 g/mol) for analytical method development and quality control.

The molecular framework of 12-Methyl-8-oxotridecanoic acid (C14H26O3) 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.
