Trimethyl Sphingosine (d18:1) (CAS 133561-52-1) is a high-purity analytical reference standard with the molecular formula C21H44NO2CH3O4S and a molecular weight of 453.68 g/mol.
The molecular framework of Trimethyl Sphingosine (d18:1) (C21H44NO2CH3O4S) is characterized by an amide group, a sulfone 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
