Chemical Structure

Potassium Methyl Sulfate CAS 562-54-9 chemical structure

Description

Potassium Methyl Sulfate (CAS 562-54-9), molecular formula CH3O4SK and molecular weight 150.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula CH3O4SK, Potassium Methyl Sulfate contains a sulfone group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 150.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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 Methyl Sulfate 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.
