Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 432.59 g/mol gives Latanoprost Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Latanoprost Impurity 19 (CAS CATO-C4X-194119), a pharmacopoeial impurity reference standard (molecular formula C26H40O5, MW 432.59 g/mol) used for the identification and quantification of trace impurities in APIs.
Latanoprost Impurity 19 (C26H40O5) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
