1-(4-Methoxyphenyl)-4-(4-phenylpiperazin-1-yl)butane-1,4-dione CAS 899190-43-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Methoxyphenyl)-4-(4-phenylpiperazin-1-yl)butane-1,4-dione.

1-(4-Methoxyphenyl)-4-(4-phenylpiperazin-1-yl)butane-1,4-dione (CAS 899190-43-3) is a high-purity analytical reference standard with the molecular formula C21H24N2O3 and a molecular weight of 352.43 g/mol.

The molecular framework of 1-(4-Methoxyphenyl)-4-(4-phenylpiperazin-1-yl)butane-1,4-dione (C21H24N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
