Chemical Structure
Description
As a certified reference material (CRM), 3-Chloro-4-(3,5-dimethyl-1h-pyrazol-1-yl)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Chloro-4-(3,5-dimethyl-1h-pyrazol-1-yl)aniline (CAS 50964-19-7) is a high-purity analytical reference standard with the molecular formula C11H12ClN3 and a molecular weight of 221.69 g/mol.
3-Chloro-4-(3,5-dimethyl-1h-pyrazol-1-yl)aniline (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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
