Description

CATO supplies (2S,3R,4E)-2-amino-1-(beta-D-galactopyranosyloxy)-3-hydroxyoctadec-4-ene (2S,3R,4E)-2-amino-3-hydroxyoctadec-4-en-1-yl beta-D-galactopyranoside 1-O-beta-D-galactopyranosylsphingosine 1-O-beta-D-galactosylsphingosine 1-beta-D-galactosphingosine 1-beta-D-galactosylsphingosine 2238-90-6 CHEBI:16874 beta-psychosine psychosine sphingosine galactoside (CAS 2238-90-6), a certified reference material (molecular formula C24H47NO7, MW 461.63 g/mol) for analytical method development and quality control.

The molecular framework of (2S,3R,4E)-2-amino-1-(beta-D-galactopyranosyloxy)-3-hydroxyoctadec-4-ene (2S,3R,4E)-2-amino-3-hydroxyoctadec-4-en-1-yl beta-D-galactopyranoside 1-O-beta-D-galactopyranosylsphingosine 1-O-beta-D-galactosylsphingosine 1-beta-D-galactosphingosine 1-beta-D-galactosylsphingosine 2238-90-6 CHEBI:16874 beta-psychosine psychosine sphingosine galactoside (C24H47NO7) is characterized by an amide 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.

As a certified reference material (CRM), (2S,3R,4E)-2-amino-1-(beta-D-galactopyranosyloxy)-3-hydroxyoctadec-4-ene (2S,3R,4E)-2-amino-3-hydroxyoctadec-4-en-1-yl beta-D-galactopyranoside 1-O-beta-D-galactopyranosylsphingosine 1-O-beta-D-galactosylsphingosine 1-beta-D-galactosphingosine 1-beta-D-galactosylsphingosine 2238-90-6 CHEBI:16874 beta-psychosine psychosine sphingosine galactoside 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.
