Chemical Structure
Description
The occurrence of Terbinafine-d7 Hydrochloride is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Terbinafine-d7 Hydrochloride (CAS 1185240-27-0) is a high-purity analytical reference standard with the molecular formula C21H18D7NHCl and a molecular weight of 334.94 g/mol.
Terbinafine-d7 Hydrochloride (C21H18D7NHCl) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
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.
