Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Docosanoic acid, calcium salt (2:1).
Docosanoic acid, calcium salt (2:1) (CAS 3578-72-1), molecular formula C22H43O2Ca and molecular weight 379.66 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H43O2Ca, Docosanoic acid, calcium salt (2:1) 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 379.66 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 acid, calcium salt (2:1) 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.
