Advantages of Hydranal one-component reagents:
- Unlimited water capacity
- Convenient and easy to use
- The greatest flexibility in working media selection
- reduced toxicity compared to methanol based systems
- Suitable for methanol-reacting compounds, e.g. ketones and aldehydes
- Long shelf life (three years)
Improved Composition
Hydranal-Composite contains all the reactants including iodine, sulfur dioxide, and the bases imidazole and 2-methylimidazole, dissolved in diethylene glycol monoethyl ether (DEGEE). Adding 2-methylimidazole in addition to imidazole improves the stability and eliminates the formation of crystals which can interfere with the titrator’s performance.
