    Storage method

    Storage precautions Store in a cool, dry, and well-ventilated special warehouse. The warehouse temperature does not exceed 30°C and the relative humidity does not exceed 80%. Keep away from fire and heat sources. The packaging must be sealed and not in contact with air. It should be stored separately from reducing agents, acids, active metal powders, and practical chemicals, and should not be mixed. The storage area should be equipped with suitable materials to contain the leakage.

    Main Uses

    1. Used in the manufacture of aniline dyes and azo dyes, in medicine, for the separation of nickel and diamond in metallurgy, and also in organic synthesis and steel analysis.

    2. Potassium nitrite is a hair color agent allowed in my country. Potassium nitrite can also inhibit a variety of anaerobic Clostridium spores, especially Clostridium botulinum has a special inhibitory effect. my country stipulates that it can be used for curing canned livestock and poultry meat and meat products. The maximum use amount is 0.15g/kg; the residual amount (calculated as sodium nitrite) of meat products shall not exceed 0.03g/kg, and the residual amount of salted ham shall be 0.07 g/kg.

    3. Used as analytical reagent, used in medicine and organic synthesis, etc.
