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.
CATO supplies (3S)-tert-Butyldimethylsilyl Vitamin D2 SO2 Adduct (Mixture of Diastereomers) (CAS 251445-16-6), a certified reference material (molecular formula C34H58O3SSi, MW 574.97 g/mol) for analytical method development and quality control.
(3S)-tert-Butyldimethylsilyl Vitamin D2 SO2 Adduct (Mixture of Diastereomers) (C34H58O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (3S)-tert-Butyldimethylsilyl Vitamin D2 SO2 Adduct (Mixture of Diastereomers) 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.
