Chemical Structure

D-Sphingosine (HCl salt) CAS 2673-72-5 chemical structure

Description

CATO supplies D-Sphingosine (HCl salt) (CAS 2673-72-5), a certified reference material (molecular formula C18H37NO2HCl, MW 335.96 g/mol) for analytical method development and quality control.

The molecular framework of D-Sphingosine (HCl salt) (C18H37NO2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
