Metamizole EP Impurity C HCl CAS 856307-27-2

Description

Compared with other compounds in its class, the molecular weight of 253.73 g/mol gives Metamizole EP Impurity C HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Metamizole EP Impurity C HCl (CAS 856307-27-2, C12H15N3OHCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Metamizole EP Impurity C HCl is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.73 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.
