Chemical Structure
Description
ethyl (6Z,9Z,12Z,15Z,18Z)-docosa-6,9,12,15,18,21-hexaenoate (CAS CATO-C4X-280643) is a high-purity analytical reference standard with the molecular formula C24H36O2 and a molecular weight of 356.54 g/mol.
Structurally, ethyl (6Z,9Z,12Z,15Z,18Z)-docosa-6,9,12,15,18,21-hexaenoate (C24H36O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 356.54 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
