Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.28 g/mol gives Atosiban Impurity 81 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Atosiban Impurity 81 (CAS CATO-C4X-229381) is a certified pharmaceutical impurity reference standard with the molecular formula C12H19NO5 and a molecular weight of 257.28 g/mol.
Based on its molecular formula C12H19NO5, Atosiban Impurity 81 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Atosiban Impurity 81 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.
