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 Eribulin Impurity 13.
CATO supplies Eribulin Impurity 13 (CAS CATO-C4X-265013), a pharmacopoeial impurity reference standard (molecular formula C46H80O9SSi2, MW 865.36 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Eribulin Impurity 13 (C46H80O9SSi2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Eribulin Impurity 13 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.
