(1-(4-Chloro-2-fluorophenyl)-3,5-dimethyl-1H-pyrazol-4-yl)methanol CAS 2379322-67-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1-(4-Chloro-2-fluorophenyl)-3,5-dimethyl-1H-pyrazol-4-yl)methanol.

(1-(4-Chloro-2-fluorophenyl)-3,5-dimethyl-1H-pyrazol-4-yl)methanol (CAS 2379322-67-3), molecular formula C12H12ClFN2O and molecular weight 254.69 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H12ClFN2O, (1-(4-Chloro-2-fluorophenyl)-3,5-dimethyl-1H-pyrazol-4-yl)methanol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 254.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
