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'-(4-bromobenzoyl)-1-naphthohydrazide.
CATO supplies N'-(4-bromobenzoyl)-1-naphthohydrazide (CAS 84282-40-6), a certified reference material (molecular formula C18H13BrN2O2, MW 369.21 g/mol) for analytical method development and quality control.
Structurally, N'-(4-bromobenzoyl)-1-naphthohydrazide (C18H13BrN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 369.21 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures N'-(4-bromobenzoyl)-1-naphthohydrazide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
