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-(3-Chlorophenyl)-1,3-dimethyl-1h-pyrazol-5-amine (CAS 1152674-85-5), a certified reference material (molecular formula C11H12ClN3, MW 221.69 g/mol) for analytical method development and quality control.
4-(3-Chlorophenyl)-1,3-dimethyl-1h-pyrazol-5-amine (C11H12ClN3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
