Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 456.99 g/mol gives Levocabastine Impurity 1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Levocabastine Impurity 1 (CAS 80185-65-5), a certified reference material (molecular formula C26H29FN2O2HCl, MW 456.99 g/mol) for analytical method development and quality control.
Levocabastine Impurity 1 (C26H29FN2O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
