Chemical Structure

(4-Methoxyphenyl)(4-(piperazin-1-yl)phenyl)methanone CAS 704873-21-2 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 (4-Methoxyphenyl)(4-(piperazin-1-yl)phenyl)methanone.

(4-Methoxyphenyl)(4-(piperazin-1-yl)phenyl)methanone (CAS 704873-21-2), molecular formula C18H20N2O2 and molecular weight 296.36 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, (4-Methoxyphenyl)(4-(piperazin-1-yl)phenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
