CATO manufactures Ruxolitinib Impurity 156 D-Tartrate 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.
CATO supplies Ruxolitinib Impurity 156 D-Tartrate (CAS 2102675-37-4), a pharmacopoeial impurity reference standard (molecular formula C8H14N2OC4H6O6, MW 304.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ruxolitinib Impurity 156 D-Tartrate (C8H14N2OC4H6O6) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 304.30 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
