Chemical Structure
Description
The molecular framework of Phytomenadione Impurity 19 (C5H5) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO supplies Phytomenadione Impurity 19 (CAS 2143-53-5), a certified reference material (molecular formula C5H5, MW 65.09 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Phytomenadione Impurity 19 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.
