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 Potassium sodium (2R,3S,4S,5S)-2,3,4,5-tetrahydroxyhexanedioate.
Potassium sodium (2R,3S,4S,5S)-2,3,4,5-tetrahydroxyhexanedioate (CAS 36221-96-2), molecular formula C6H8O8KNa and molecular weight 270.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium sodium (2R,3S,4S,5S)-2,3,4,5-tetrahydroxyhexanedioate (C6H8O8KNa) is characterized by a carbohydrate-derived structure. 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 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).
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 manufactures Potassium sodium (2R,3S,4S,5S)-2,3,4,5-tetrahydroxyhexanedioate 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.
