Product Overview

Potassium Chloride 99.5% AR (CAS No. 7447-40-7) is analytical-reagent KCl, a well-defined 1:1 potassium chloride electrolyte. Its reproducible ionic dissociation makes it useful in conductivity, ionic-strength, electrode and analytical solution studies where controlled reagent quality is important.

The AR grade is intended for preparation of analytical KCl solutions, electrolyte systems, buffer-supporting media and conventional wet-chemical methods. It can support conductivity and electrochemical studies, but no certified conductivity-standard value is implied unless the prepared solution is separately qualified.

Typical Applications

• Preparation of analytical potassium chloride solutions
• Electrolyte preparation
• Ionic-strength adjustment
• Conductivity studies
• Electrochemical cell solutions
• Preparation of non-certified potassium working solutions
• Conventional analytical reagent preparation

Common Synonyms

• Potassium chloride
• KCl
• Potassium muriate
• Chloride of potash

Storage Conditions

Store tightly closed and dry, protected from moisture and analytical contamination. Use clean equipment during quantitative solution preparation.
