Potassium hydroxide 45% solution at ACS reagent purity — caustic potash supplied ready to use as a clear, colorless liquid at 45% w/w, with the trace-metal and chloride limits that analytical work depends on.
The ACS designation matters when results have to hold up: titration, standard solution prep, and QC methods where reagent purity drives repeatability. If the process is pH adjustment, cleaning, or general neutralization, our Potassium Hydroxide 45% Solution Technical Grade covers the same concentration at a working-grade price. Same chemistry, same handling rules — the difference is what the application demands of the certificate.
Typical applications
- Analytical titration and standard solution preparation
- QC methods requiring reagent-grade alkali
- Laboratory pH adjustment and neutralization
- Research synthesis where trace metals interfere
- Electroless plating baths and metal surface treatment

Shipping and handling
UN1814, Potassium hydroxide solution, Class 8, PG II. Corrosive — causes severe skin burns and eye damage. Wear chemical splash goggles, face shield, and chemical-resistant gloves. Store in a closed container away from acids and reactive metals. Always add caustic to water, never water to caustic.
A Safety Data Sheet ships with every order and is available on request before purchase. A lot-specific Certificate of Analysis is available for the material you receive.
