Chemical Structure

27888-44-4 C22 Ceramide (d18:1/22:0) CAS 27888-44-4 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.

CATO supplies 27888-44-4 C22 Ceramide (d18:1/22:0) (CAS 27888-44-4), a certified reference material (molecular formula C40H79NO3, MW 622.06 g/mol) for analytical method development and quality control.

27888-44-4 C22 Ceramide (d18:1/22:0) (C40H79NO3) contains an amide group, 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 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.
