Tandospirone Impurity 18 CAS CATO-C4X-187518 chemical structure

Description

Tandospirone Impurity 18 (CAS CATO-C4X-187518) is a certified pharmaceutical impurity reference standard with the molecular formula C16H28N6HCl and a molecular weight of 340.90 g/mol.

Tandospirone Impurity 18 (C16H28N6HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Tandospirone Impurity 18 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.
