Chemical Structure
Description
3-Cyclopropyl-4-iodo-2H-pyrazole (CAS 1341758-26-6), molecular formula C6H7IN2 and molecular weight 234.04 g/mol, is a CATO reference standard with documented purity and traceability.
3-Cyclopropyl-4-iodo-2H-pyrazole (C6H7IN2) contains a nitrile group, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 3-Cyclopropyl-4-iodo-2H-pyrazole 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.
