Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 485.56 g/mol gives Baricitinib Impurity 44 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Baricitinib Impurity 44 (CAS 1187595-90-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H27N7O4S and a molecular weight of 485.56 g/mol.
Based on its molecular formula C22H27N7O4S, Baricitinib Impurity 44 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 485.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures Baricitinib Impurity 44 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.
