Application
- Rediscover Potassium Permanganate as a Stain for Basic Proteins on Ultrathin Sections at Transmission Electron Microscopy.: This study explores the reapplication of potassium permanganate as a staining agent for basic proteins in transmission electron microscopy, demonstrating its effectiveness in enhancing protein visualization (Zannino et al., 2023).
- Core-satellite surface imprinting polymer-based pipette tip solid-phase extraction for the colorimetric determination of pyrethroid metabolite.: This study presents a novel method using potassium permanganate in core-satellite surface imprinting for efficient extraction and colorimetric analysis of pyrethroid metabolites in environmental samples (Ye et al., 2020).

Remarque sur l'analyse
Form liquid
Amount-of-substance concentration 0.04975 - 0.05025 mol/L
Measurement uncertainty ± 0.00015 mol/L
Traceability NIST SRM
The concentration is determined by volumetric titration and refers to 20°C.
The amount-of-substance concentration of this volumetric solution is traceable to a primary standard reference material (SRM) from the National Institute of Standards and Technology, Gaithersburg, USA (NIST SRM 8040 di-sodium oxalate) by means of volumetric standard di-sodium oxalate (article number 1.02407), certified reference material according to ISO 17034, analyzed by our accredited calibration laboratory of Merck KGaA, Darmstadt, Germany according to DIN EN ISO/IEC 17025. The uncertainty is expressed as expanded measurement uncertainty with a coverage factor k=2 covering a confidence level of 95%.
Note: The titer is a correction factor to correct for variations of the volumetric solution, the titration equipment, the temperature and other laboratory conditions. For correct titration results it is recommended to determine a titer with the laboratory specific equipment and under laboratory specific conditions directly after opening a new bottle and at regular time intervals.
