Chemical Structure

Docosanedioic acid CAS 505-56-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 340.58 g/mol gives Docosanedioic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Docosanedioic acid (CAS 505-56-6), a certified reference material (molecular formula C22H44O2, MW 340.58 g/mol) for analytical method development and quality control.

Docosanedioic acid (C22H44O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
