4-Iodo-1-[(4-methoxyphenyl)methyl]-3,5-dimethyl-1H-pyrazole CAS 374756-59-9

Description

4-Iodo-1-[(4-methoxyphenyl)methyl]-3,5-dimethyl-1H-pyrazole (CAS 374756-59-9), molecular formula C13H15IN2O and molecular weight 342.18 g/mol, is a CATO reference standard with documented purity and traceability.

4-Iodo-1-[(4-methoxyphenyl)methyl]-3,5-dimethyl-1H-pyrazole (C13H15IN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4-Iodo-1-[(4-methoxyphenyl)methyl]-3,5-dimethyl-1H-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.
