Chemical Structure
Description
The occurrence of Ramosetron Impurity 12 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ramosetron Impurity 12 (CAS 171967-74-1) is a certified pharmaceutical impurity reference standard with the molecular formula C17H19N3O4 and a molecular weight of 329.35 g/mol.
Based on its molecular formula C17H19N3O4, Ramosetron Impurity 12 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 329.35 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 Ramosetron Impurity 12 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.
