Chemical Structure

Potassium O-methyl carbonodithioate CAS 2667-20-1 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 O-methyl carbonodithioate.

CATO supplies Potassium O-methyl carbonodithioate (CAS 2667-20-1), a certified reference material (molecular formula C2H3OS2K, MW 146.26 g/mol) for analytical method development and quality control.

The molecular framework of Potassium O-methyl carbonodithioate (C2H3OS2K) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 O-methyl carbonodithioate 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.
