5-Chloro-4-(methoxy(phenyl)methyl)-1-methyl-3-phenyl-1H-pyrazole CAS 956181-56-9

Description

Compared with other compounds in its class, the molecular weight of 312.79 g/mol gives 5-Chloro-4-(methoxy(phenyl)methyl)-1-methyl-3-phenyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-4-(methoxy(phenyl)methyl)-1-methyl-3-phenyl-1H-pyrazole (CAS 956181-56-9) is a high-purity analytical reference standard with the molecular formula C18H17ClN2O and a molecular weight of 312.79 g/mol.

5-Chloro-4-(methoxy(phenyl)methyl)-1-methyl-3-phenyl-1H-pyrazole (C18H17ClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.

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.
