Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N4-(2,4-Difluorophenyl)-N2-hexyl-L-asparagine.
N4-(2,4-Difluorophenyl)-N2-hexyl-L-asparagine (CAS 1048011-75-1), molecular formula C16H22F2N2O3 and molecular weight 328.35 g/mol, is a CATO reference standard with documented purity and traceability.
N4-(2,4-Difluorophenyl)-N2-hexyl-L-asparagine (C16H22F2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
