Chemical Structure

D-threo-1-(4-Aminophenyl)-2-dichloroacetylamino-1,3-propanediol Hydrochloride CAS 57704-36-6 chemical structure

Description

The occurrence of D-threo-1-(4-Aminophenyl)-2-dichloroacetylamino-1,3-propanediol Hydrochloride 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.

D-threo-1-(4-Aminophenyl)-2-dichloroacetylamino-1,3-propanediol Hydrochloride (CAS 57704-36-6) is a high-purity analytical reference standard with the molecular formula C11H14Cl2N2O3HCl and a molecular weight of 329.60 g/mol.

D-threo-1-(4-Aminophenyl)-2-dichloroacetylamino-1,3-propanediol Hydrochloride (C11H14Cl2N2O3HCl) 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), D-threo-1-(4-Aminophenyl)-2-dichloroacetylamino-1,3-propanediol Hydrochloride 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.
