Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Chloro-1-methyl-1h-pyrazol-5-yl)methanamine.
CATO supplies (4-Chloro-1-methyl-1h-pyrazol-5-yl)methanamine (CAS 1001500-75-9), a certified reference material (molecular formula C5H8ClN3, MW 145.59 g/mol) for analytical method development and quality control.
The molecular framework of (4-Chloro-1-methyl-1h-pyrazol-5-yl)methanamine (C5H8ClN3) is characterized by a nitrile group, 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.
