Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tivozanib Impurity 2.
As a process- or degradation-related impurity, Tivozanib Impurity 2 (CAS CATO-C4X-34002, C17H16N2O5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Tivozanib Impurity 2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.38 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 Tivozanib Impurity 2 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.
