Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 381.49 g/mol gives D-erythro-Dihydro-D-sphingosine-1-phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies D-erythro-Dihydro-D-sphingosine-1-phosphate (CAS 19794-97-9), a certified reference material (molecular formula C18H40NO5P, MW 381.49 g/mol) for analytical method development and quality control.
The molecular framework of D-erythro-Dihydro-D-sphingosine-1-phosphate (C18H40NO5P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
