Chemical Structure
Description
The occurrence of 5-Chloro-1-(3-chlorophenyl)-1H-pyrazole-4-carbonitrile 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.
5-Chloro-1-(3-chlorophenyl)-1H-pyrazole-4-carbonitrile (CAS 102996-33-8) is a high-purity analytical reference standard with the molecular formula C10H5Cl2N3 and a molecular weight of 238.07 g/mol.
5-Chloro-1-(3-chlorophenyl)-1H-pyrazole-4-carbonitrile (C10H5Cl2N3) 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), 5-Chloro-1-(3-chlorophenyl)-1H-pyrazole-4-carbonitrile 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.
