Chemical Structure
Description
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.
3-O-(tert-Butyldimethylsilyloxy)-erythro-sphingosine (CAS 137905-29-4) is a high-purity analytical reference standard with the molecular formula C24H51NO2Si and a molecular weight of 413.75 g/mol.
The molecular framework of 3-O-(tert-Butyldimethylsilyloxy)-erythro-sphingosine (C24H51NO2Si) 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 its high hydrophobicity (logP), 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.
As a certified reference material (CRM), 3-O-(tert-Butyldimethylsilyloxy)-erythro-sphingosine 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.
