Description
Ammonium Hydroxide 25% Solution
Ammonium Hydroxide 25% Solution (CAS 1336-21-6, molecular formula NH4OH) is a core commodity reagent used wherever reliable acid or alkali strength matters — from surface treatment and pH correction to downstream salt manufacture. China Chemicals supplies it at 25% w/w in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Aqueous Ammonia, Ammonia Solution, Ammonia Water. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
Typical applications
- Flue gas NOx reduction (SNCR / SCR)
- pH adjustment in water and boiler treatment
- Latex stabilisation in rubber processing
- Textile and paper processing
- Industrial and glass cleaning formulations
