Levetiracetam EP Impurity G CAS 7682-20-4 chemical structure

Description

CATO manufactures Levetiracetam EP Impurity G 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.

As a process- or degradation-related impurity, Levetiracetam EP Impurity G (CAS 7682-20-4, C4H10N2OHCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Levetiracetam EP Impurity G is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.59 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.
