Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n-(4-Fluorobenzyl)-2-((4-methyl-5-(m-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetamide (CAS 848832-73-5), molecular formula C19H19FN4OS and molecular weight 370.44 g/mol, is a CATO reference standard with documented purity and traceability.
n-(4-Fluorobenzyl)-2-((4-methyl-5-(m-tolyl)-4h-1,2,4-triazol-3-yl)thio)acetamide (C19H19FN4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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).
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.
