Chemical Structure
Description
The occurrence of buta-2,3-dien-1-amine hydrochloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies buta-2,3-dien-1-amine hydrochloride (CAS 473742-53-9), a certified reference material (molecular formula C4H7NHCl, MW 105.56 g/mol) for analytical method development and quality control.
The molecular framework of buta-2,3-dien-1-amine hydrochloride (C4H7NHCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
