Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N,N-Dimethyl-1,4-phenylenediamine Dihydrochloride (CAS 536-46-9), a certified reference material (molecular formula C8H12N2HCl, MW 172.66 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, N,N-Dimethyl-1,4-phenylenediamine Dihydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 172.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
