Chemical Structure

Potassium Peroxymonosulfate Sulfate CAS 37222-66-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Potassium Peroxymonosulfate Sulfate (CAS 37222-66-5), a certified reference material (molecular formula HO5SHO4SO4SK, MW 345.28 g/mol) for analytical method development and quality control.

The molecular framework of Potassium Peroxymonosulfate Sulfate (HO5SHO4SO4SK) is characterized by a sulfone group. 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.

As a certified reference material (CRM), Potassium Peroxymonosulfate 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.
