(Z)-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}methylidene)(methyl)oxidoazanium CAS 338770-38-0

Description

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.

(Z)-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}methylidene)(methyl)oxidoazanium (CAS 338770-38-0), molecular formula C16H11ClF3N3O and molecular weight 353.73 g/mol, is a CATO reference standard with documented purity and traceability.

(Z)-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-indol-3-yl}methylidene)(methyl)oxidoazanium (C16H11ClF3N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
