Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ibutilide Impurity 11.
CATO supplies Ibutilide Impurity 11 (CAS CATO-C4X-211011), a pharmacopoeial impurity reference standard (molecular formula C20H34N2O2S, MW 366.56 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ibutilide Impurity 11 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Ibutilide Impurity 11 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.
