Chemical Structure

N'-(2-Methylbenzoyl)-2-naphthohydrazide CAS 83803-94-5 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 N'-(2-Methylbenzoyl)-2-naphthohydrazide.

N'-(2-Methylbenzoyl)-2-naphthohydrazide (CAS 83803-94-5) is a high-purity analytical reference standard with the molecular formula C19H16N2O2 and a molecular weight of 304.34 g/mol.

The molecular framework of N'-(2-Methylbenzoyl)-2-naphthohydrazide (C19H16N2O2) 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 its high hydrophobicity (logP), 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).

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.

As a certified reference material (CRM), N'-(2-Methylbenzoyl)-2-naphthohydrazide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
