Chemical Structure
Description
The occurrence of 4-Methoxy-N1-methylbenzene-1,2-diamine dihydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methoxy-N1-methylbenzene-1,2-diamine dihydrochloride (CAS 55783-46-5), molecular formula C8H12N2OHCl and molecular weight 188.66 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Methoxy-N1-methylbenzene-1,2-diamine dihydrochloride (C8H12N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 188.66 g/mol, it falls into the medium-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.
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.
