Chemical Structure
Description
1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-(2-{3-[(1Z)-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-ylidene}methyl]phenoxy}ethyl)piperazine (CAS 338409-21-5) is a high-purity analytical reference standard with the molecular formula C25H22Cl2F6N6O and a molecular weight of 607.38 g/mol.
1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-(2-{3-[(1Z)-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]hydrazin-1-ylidene}methyl]phenoxy}ethyl)piperazine (C25H22Cl2F6N6O) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
