Description
CATO manufactures Grapiprant Impurity 2 TriHCl 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.
Grapiprant Impurity 2 TriHCl (CAS CATO-C4X-33892) is a certified pharmaceutical impurity reference standard with the molecular formula C18H22N4HCl and a molecular weight of 330.86 g/mol.
Based on its molecular formula C18H22N4HCl, Grapiprant Impurity 2 TriHCl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
