Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6918-49-6 D-erythro-sphingosine (C20 base) Sphingosine (d20:1) (CAS 6918-49-6), a certified reference material (molecular formula C20H41NO2, MW 327.55 g/mol) for analytical method development and quality control.
6918-49-6 D-erythro-sphingosine (C20 base) Sphingosine (d20:1) (C20H41NO2) 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.
CATO manufactures 6918-49-6 D-erythro-sphingosine (C20 base) Sphingosine (d20:1) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
