1-[1-(4-fluorophenyl)-5-methyl-1h-1,2,3-triazol-4-yl]ethan-1-one CAS 1017471-25-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[1-(4-fluorophenyl)-5-methyl-1h-1,2,3-triazol-4-yl]ethan-1-one.

1-[1-(4-fluorophenyl)-5-methyl-1h-1,2,3-triazol-4-yl]ethan-1-one (CAS 1017471-25-8) is a high-purity analytical reference standard with the molecular formula C11H10FN3O and a molecular weight of 219.22 g/mol.

1-[1-(4-fluorophenyl)-5-methyl-1h-1,2,3-triazol-4-yl]ethan-1-one (C11H10FN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.

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.
