Docosanoic anhydride CAS 55726-23-3

Description

Compared with other compounds in its class, the molecular weight of 663.15 g/mol gives Docosanoic anhydride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Docosanoic anhydride (CAS 55726-23-3), molecular formula C44H86O3 and molecular weight 663.15 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C44H86O3, Docosanoic anhydride contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 663.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Docosanoic anhydride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
