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-(Diphenylamino)benzaldehyde diphenylhydrazone.
CATO supplies 4-(Diphenylamino)benzaldehyde diphenylhydrazone (CAS 82532-76-1), a certified reference material (molecular formula C31H25N3, MW 439.55 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-(Diphenylamino)benzaldehyde diphenylhydrazone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
