3-tert-Butyl-1-(2,4-Dichlorophenyl)-1H-pyrazol-5-amine CAS 1017781-18-8 chemical structure

Description

The occurrence of 3-tert-Butyl-1-(2,4-Dichlorophenyl)-1H-pyrazol-5-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-tert-Butyl-1-(2,4-Dichlorophenyl)-1H-pyrazol-5-amine (CAS 1017781-18-8), molecular formula C13H15Cl2N3 and molecular weight 284.18 g/mol, is a CATO reference standard with documented purity and traceability.

3-tert-Butyl-1-(2,4-Dichlorophenyl)-1H-pyrazol-5-amine (C13H15Cl2N3) 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.

As a certified reference material (CRM), 3-tert-Butyl-1-(2,4-Dichlorophenyl)-1H-pyrazol-5-amine 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.
