Chemical Structure
Description
CATO supplies 5-methyl-1-(4-methylphenyl)-1H-pyrazol-4-amine hydrochloride (CAS 1909313-94-5), a certified reference material (molecular formula C11H13N3HCl, MW 223.70 g/mol) for analytical method development and quality control.
5-methyl-1-(4-methylphenyl)-1H-pyrazol-4-amine hydrochloride (C11H13N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
