Potassium Hydroxide (KOH) / Caustic Potash

High-Purity Strong Base for Laboratory, Industrial & Food Applications
Catalog Number: ASC-1067

Overview

Potassium Hydroxide (KOH), commonly known as caustic potash, is a strong inorganic base widely used across laboratory, industrial, food, pharmaceutical, and chemical manufacturing sectors. Supplied as a white, deliquescent solid (pellets, flakes, or powder), KOH is highly soluble in water and releases heat upon dissolution, making it a powerful and efficient alkalizing and reactive agent.

Ausamics Potassium Hydroxide (ASC-1067) is supplied to ACS-grade specifications, ensuring reliable performance in demanding analytical and production environments.
