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 2-(3,5-Dimethoxybenzoyl)-N-(naphthalen-1-yl)hydrazinecarboxamide.
2-(3,5-Dimethoxybenzoyl)-N-(naphthalen-1-yl)hydrazinecarboxamide (CAS 444932-31-4) is a high-purity analytical reference standard with the molecular formula C20H19N3O4 and a molecular weight of 365.38 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2-(3,5-Dimethoxybenzoyl)-N-(naphthalen-1-yl)hydrazinecarboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
