The occurrence of Ivacaftor Impurity 9 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ivacaftor Impurity 9 (CAS 26892-90-0) is a certified pharmaceutical impurity reference standard with the molecular formula C12H11NO3 and a molecular weight of 217.22 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ivacaftor Impurity 9 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Ivacaftor Impurity 9 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.
