Description
Nitric Acid 68% Technical Grade
Nitric Acid 68% Technical Grade (CAS 7697-37-2, molecular formula HNO3) 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 68% 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 Aqua Fortis, Spirit of Nitre. 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
- Ammonium nitrate and fertiliser production
- Stainless steel passivation and pickling
- Metal etching and electronics processing
- Nitration reactions in fine chemical synthesis
- Analytical digestion and laboratory use
