General description
Sulfamic acid, a strong inorganic acid, exists in crystalline form. It is stable, non-hygroscopic, odorless, and colorless in dry state, making its commercial packaging and handling convenient.
Application
It can be used as an acidimetric standard for analytical applications.
Sulfamic acid also finds its use as a primary standard in non-aqueous visual, conductometric, and potentiometric titrations.
Sulfamic acid also finds its use as a primary standard in non-aqueous visual, conductometric, and potentiometric titrations.
Features and Benefits
- Available in a secure glass bottle to ensure its stability for the entire shelf life until opened.
- High-quality offering accurate titer determinations
- Accompanied by a detailed certificate of analysis (CoA)
