Chemical Structure
Description
The molecular framework of Tert-butyl (S)-6-(((tert-butyldimethylsilyl)oxy)methyl)-4-methyl-3-oxo-3,6-dihydropyridine-1(2H)-carboxylate (C18H33NO4Si) 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.
Tert-butyl (S)-6-(((tert-butyldimethylsilyl)oxy)methyl)-4-methyl-3-oxo-3,6-dihydropyridine-1(2H)-carboxylate (CAS 1467157-44-3), molecular formula C18H33NO4Si and molecular weight 355.54 g/mol, is a CATO reference standard with documented purity and traceability.
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.
