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 4-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-5-amine (CAS 2484774-19-6), a certified reference material (molecular formula C5H6ClF2N3, MW 181.57 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-3-(difluoromethyl)-1-methyl-1H-pyrazol-5-amine (C5H6ClF2N3) contains a nitrile group, fluorine/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 181.57 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.
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.
