Chemical Structure
Description
As a certified reference material (CRM), n-(2,5-Dichlorophenyl)-2-{[(3,4-dimethoxyphenyl)methyl]amino}propanamide 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.
n-(2,5-Dichlorophenyl)-2-{[(3,4-dimethoxyphenyl)methyl]amino}propanamide (CAS 1049727-35-6) is a high-purity analytical reference standard with the molecular formula C18H20Cl2N2O3 and a molecular weight of 383.27 g/mol.
n-(2,5-Dichlorophenyl)-2-{[(3,4-dimethoxyphenyl)methyl]amino}propanamide (C18H20Cl2N2O3) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
