Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(3-Chlorophenyl)-3-(1-oxo-4-phenylphthalazin-2(1H)-yl)propanamide (CAS 836640-15-4), molecular formula C23H18ClN3O2 and molecular weight 403.86 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3-Chlorophenyl)-3-(1-oxo-4-phenylphthalazin-2(1H)-yl)propanamide (C23H18ClN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), N-(3-Chlorophenyl)-3-(1-oxo-4-phenylphthalazin-2(1H)-yl)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.
