Chemical Structure

15(S)-HETE methyl ester CAS 70946-44-0 chemical structure

Description

15(S)-HETE methyl ester (CAS 70946-44-0) is a high-purity analytical reference standard with the molecular formula C21H34O3 and a molecular weight of 334.49 g/mol.

Based on its molecular formula C21H34O3, 15(S)-HETE methyl ester 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 334.49 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), 15(S)-HETE methyl ester 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.
