5-(4-Fluorophenyl)-1-methyl-1H-pyrazole-4-carbaldehyde CAS 689250-52-0

Description

The occurrence of 5-(4-Fluorophenyl)-1-methyl-1H-pyrazole-4-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(4-Fluorophenyl)-1-methyl-1H-pyrazole-4-carbaldehyde (CAS 689250-52-0), molecular formula C11H9FN2O and molecular weight 204.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H9FN2O, 5-(4-Fluorophenyl)-1-methyl-1H-pyrazole-4-carbaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-(4-Fluorophenyl)-1-methyl-1H-pyrazole-4-carbaldehyde 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.
