Chemical Structure
Description
The occurrence of (2,6-Dichloropyridin-4-yl)methyl (3-(2,6-dichlorophenyl)-5-methylisoxazol-4-yl)carbamate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,6-Dichloropyridin-4-yl)methyl (3-(2,6-dichlorophenyl)-5-methylisoxazol-4-yl)carbamate (CAS 261622-75-7), molecular formula C17H11Cl4N3O3 and molecular weight 447.10 g/mol, is a CATO reference standard with documented purity and traceability.
(2,6-Dichloropyridin-4-yl)methyl (3-(2,6-dichlorophenyl)-5-methylisoxazol-4-yl)carbamate (C17H11Cl4N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
