Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies Calcium Levofolinate Pentahydrate - Impurity G (Dihydrate Salt) (CAS 207226-40-2), a certified reference material (molecular formula C19H21N7O6H2O, MW 461.44 g/mol) for analytical method development and quality control.
The molecular framework of Calcium Levofolinate Pentahydrate - Impurity G (Dihydrate Salt) (C19H21N7O6H2O) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 manufactures Calcium Levofolinate Pentahydrate - Impurity G (Dihydrate Salt) 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.
