D-erythro-Sphingosine sulfate salt CAS 56607-20-6

Description

As a certified reference material (CRM), D-erythro-Sphingosine sulfate salt 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.

D-erythro-Sphingosine sulfate salt (CAS 56607-20-6), molecular formula C18H35NO2H2O4S and molecular weight 395.56 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H35NO2H2O4S, D-erythro-Sphingosine sulfate salt contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 395.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
