Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(1,4-dioxo-3-(4-phenylpiperazin-1-yl)-1,4-dihydronaphthalen-2-yl)benzamide.
N-(1,4-dioxo-3-(4-phenylpiperazin-1-yl)-1,4-dihydronaphthalen-2-yl)benzamide (CAS 1640259-27-3), molecular formula C27H23N3O3 and molecular weight 437.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(1,4-dioxo-3-(4-phenylpiperazin-1-yl)-1,4-dihydronaphthalen-2-yl)benzamide (C27H23N3O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
