Chemical Structure
Description
The occurrence of N4-(3-Chloro-2-methylphenyl)-N2-(2-hydroxypropyl)-L-asparagine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N4-(3-Chloro-2-methylphenyl)-N2-(2-hydroxypropyl)-L-asparagine (CAS 1047683-11-3), a certified reference material (molecular formula C14H19ClN2O4, MW 314.76 g/mol) for analytical method development and quality control.
N4-(3-Chloro-2-methylphenyl)-N2-(2-hydroxypropyl)-L-asparagine (C14H19ClN2O4) contains a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N4-(3-Chloro-2-methylphenyl)-N2-(2-hydroxypropyl)-L-asparagine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
