Chemical Structure
Description
The occurrence of 5-chloro-3-methyl-1H-pyrazol-4-amine is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-chloro-3-methyl-1H-pyrazol-4-amine (CAS 1064687-15-5), a certified reference material (molecular formula C4H10ClN3, MW 135.60 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, 5-chloro-3-methyl-1H-pyrazol-4-amine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.60 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.
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.
