Chemical Structure
Description
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.
CATO supplies 4,4'-Methylenebis(3-chloro-N,N-dimethylaniline) (CAS 5428-29-5), a certified reference material (molecular formula C17H20Cl2N2, MW 323.26 g/mol) for analytical method development and quality control.
Structurally, 4,4'-Methylenebis(3-chloro-N,N-dimethylaniline) (C17H20Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 323.26 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
