Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Conjugated Linoleic Acid Ethyl Ester, 90% (Mixture of Isomers) (CAS 137142-61-1), molecular formula C20H36O2 and molecular weight 308.50 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Conjugated Linoleic Acid Ethyl Ester, 90% (Mixture of Isomers) (C20H36O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 308.50 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.
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.
