Chemical Structure

Potassium Bitartrate CAS 868-14-4 chemical structure

Description

CATO supplies Potassium Bitartrate (CAS 868-14-4), a certified reference material (molecular formula C4H5O6K, MW 188.18 g/mol) for analytical method development and quality control.

The molecular framework of Potassium Bitartrate (C4H5O6K) 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.

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.

As a certified reference material (CRM), Potassium Bitartrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
