Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ethyl (5Z,8Z,11E,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate.
CATO supplies ethyl (5Z,8Z,11E,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate (CAS CATO-C4X-28907), a certified reference material (molecular formula C22H34O2, MW 330.50 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H34O2, ethyl (5Z,8Z,11E,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.50 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), ethyl (5Z,8Z,11E,14Z,17Z)-icosa-5,8,11,14,17-pentaenoate 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.
