The role of thiocyanate

2025-05-26

In chemical analysis, thiocyanates are often used for the qualitative analysis of iron(III) ions.

  Thiocyanates have multiple functions, including applications in chemical analysis, therapeutic effects on skin fungal infections, and their natural presence and preservative effects in milk.
  Applications in Chemical Analysis
  In chemical analysis, thiocyanates are often used for the qualitative analysis of iron(III) ions. Their reactive properties make thiocyanates an important chemical reagent.
  Treatment of Skin Fungal Infections
  Sodium thiocyanate is often used clinically to treat skin fungal infections, exhibiting a certain fungicidal effect. Therefore, sodium thiocyanate has a certain therapeutic effect on fungal infection-related hair loss, but the specific effect varies from person to person. It should be used under the guidance of a physician to avoid adverse reactions.
  Natural Presence and Preservative Effect in Milk
  Thiocyanate is a key component of the lactoperoxidase antimicrobial system (LPS) in milk, effectively inhibiting and killing various microorganisms. The level of thiocyanate in cow's milk is mainly affected by thiocyanate and its precursor substances in the feed, such as glucosinolates in cruciferous plants. These substances produce thiocyanate through hydrolysis by myrosinase after damage to plant tissue. Because cruciferous plants are often used as protein supplements for dairy cows, the thiocyanate in raw milk also originates from this. In addition, sodium thiocyanate is widely used in industry as a preservative to ensure the safe transportation of milk without refrigeration.
