Rotigotine EP Impurity B HCl CAS 1231158-77-2

Description

Compared with other compounds in its class, the molecular weight of 241.76 g/mol gives Rotigotine EP Impurity B HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Rotigotine EP Impurity B HCl (CAS 1231158-77-2) is a certified pharmaceutical impurity reference standard with the molecular formula C13H19NOHCl and a molecular weight of 241.76 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Rotigotine EP Impurity B HCl is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

CATO manufactures Rotigotine EP Impurity B HCl under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
