Chemical Structure
Description
D-galactosyl-ß-1,1' N-nervonoyl-D-erythro-sphingosine (CAS 17283-91-9) is a high-purity analytical reference standard with the molecular formula C48H91NO8 and a molecular weight of 810.24 g/mol.
D-galactosyl-ß-1,1' N-nervonoyl-D-erythro-sphingosine (C48H91NO8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
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.
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.
