Description

Compared with other compounds in its class, the molecular weight of 276.19 g/mol gives 5-((3,5-Bis(difluoromethyl)-1H-pyrazol-1-yl)methyl)furan-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-((3,5-Bis(difluoromethyl)-1H-pyrazol-1-yl)methyl)furan-2-carbaldehyde (CAS 895930-59-3) is a high-purity analytical reference standard with the molecular formula C11H8F4N2O2 and a molecular weight of 276.19 g/mol.

The molecular framework of 5-((3,5-Bis(difluoromethyl)-1H-pyrazol-1-yl)methyl)furan-2-carbaldehyde (C11H8F4N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
