Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.69 g/mol gives Benserazide Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benserazide Impurity 8 (CAS CATO-C4X-14278) is a certified pharmaceutical impurity reference standard with the molecular formula C10H13N3O5HCl and a molecular weight of 291.69 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Benserazide Impurity 8 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
