Chemical Structure

Fluralaner Impurity 5 CAS 1171331-39-7 chemical structure

Description

Fluralaner Impurity 5 (C4H7F3N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.

Fluralaner Impurity 5 (CAS 1171331-39-7) is a certified pharmaceutical impurity reference standard with the molecular formula C4H7F3N2OHCl and a molecular weight of 192.56 g/mol.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
