12-Oxododecanoic acid CAS 3956-80-7

Description

Compared with other compounds in its class, the molecular weight of 214.30 g/mol gives 12-Oxododecanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 12-Oxododecanoic acid (CAS 3956-80-7), a certified reference material (molecular formula C12H22O3, MW 214.30 g/mol) for analytical method development and quality control.

12-Oxododecanoic acid (C12H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
