Ethyl Stearate-d5 CAS 1216808-22-8 chemical structure

Description

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.

Ethyl Stearate-d5 (CAS 1216808-22-8), molecular formula C20H35D5O2 and molecular weight 317.56 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl Stearate-d5 (C20H35D5O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
