Chemical Structure

D-ribo Phytosphingosine CAS 554-62-1 chemical structure

Description

D-ribo Phytosphingosine (CAS 554-62-1), molecular formula C18H39NO3 and molecular weight 317.51 g/mol, is a CATO reference standard with documented purity and traceability.

D-ribo Phytosphingosine (C18H39NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

As a certified reference material (CRM), D-ribo Phytosphingosine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
