Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-((2-Chloro-6-fluorobenzyl)oxy)-2-methyl-1-(4-methylbenzyl)pyridin-4(1H)-one (CAS 303144-69-6), a certified reference material (molecular formula C21H19ClFNO2, MW 371.83 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H19ClFNO2, 3-((2-Chloro-6-fluorobenzyl)oxy)-2-methyl-1-(4-methylbenzyl)pyridin-4(1H)-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
