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-Fluorobenzenecarbaldehyde N-(3-benzyl-2-quinoxalinyl)hydrazone.
4-Fluorobenzenecarbaldehyde N-(3-benzyl-2-quinoxalinyl)hydrazone (CAS 478064-31-2) is a high-purity analytical reference standard with the molecular formula C22H17FN4 and a molecular weight of 356.40 g/mol.
The molecular framework of 4-Fluorobenzenecarbaldehyde N-(3-benzyl-2-quinoxalinyl)hydrazone (C22H17FN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. 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. 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.
