Chemical Structure
Description
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.
3-(Dimethylamino)propyl 4-oxo-3-phenyl-3,4-dihydrophthalazine-1-carboxylate hydrochloride (CAS 21131-15-7), molecular formula C20H21N3O3HCl and molecular weight 387.86 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(Dimethylamino)propyl 4-oxo-3-phenyl-3,4-dihydrophthalazine-1-carboxylate hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 387.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 3-(Dimethylamino)propyl 4-oxo-3-phenyl-3,4-dihydrophthalazine-1-carboxylate hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
