Chemical Structure

Henicosan-11-one CAS 19781-72-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 310.56 g/mol gives Henicosan-11-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Henicosan-11-one (CAS 19781-72-7), molecular formula C21H42O and molecular weight 310.56 g/mol, is a CATO reference standard with documented purity and traceability.

Henicosan-11-one (C21H42O) contains a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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), Henicosan-11-one 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.
