3-O-tert-Butyldimethylsilyl-D-Erythro-sphingosylphosphorylcholine CAS 168411-99-2 chemical structure

Description

The occurrence of 3-O-tert-Butyldimethylsilyl-D-Erythro-sphingosylphosphorylcholine is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-O-tert-Butyldimethylsilyl-D-Erythro-sphingosylphosphorylcholine (CAS 168411-99-2), a certified reference material (molecular formula C29H63N2O5PSi, MW 578.88 g/mol) for analytical method development and quality control.

3-O-tert-Butyldimethylsilyl-D-Erythro-sphingosylphosphorylcholine (C29H63N2O5PSi) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

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.
