Description

124863-82-7 3-tert-Butyldimethylsilyloxymethyl-2,6-diisopropyl-4-(4-fluorophenyl)-5-hydroxymethyl-pyridine 5-[[[(1,1-Dimethylethyl)dimethylsilyl]oxy]methyl]-4-(4-fluorophenyl)-2,6-bis(1-methylethyl)-3-pyridinemethanol (CAS 124863-82-7), molecular formula C25H38FNO2Si and molecular weight 431.66 g/mol, is a CATO reference standard with documented purity and traceability.

124863-82-7 3-tert-Butyldimethylsilyloxymethyl-2,6-diisopropyl-4-(4-fluorophenyl)-5-hydroxymethyl-pyridine 5-[[[(1,1-Dimethylethyl)dimethylsilyl]oxy]methyl]-4-(4-fluorophenyl)-2,6-bis(1-methylethyl)-3-pyridinemethanol (C25H38FNO2Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
