Tetrahedron has developed new synthetic processes allowing the industrial production of the following known compounds:
- L-(+)-ergothioneine, a natural antioxidant
Tetrahedron has also designed new and proprietary antioxidants, which are selenoorganic compounds:
- The basic structure is NutraSelen® (THD-177) which is a novel organic source of selenium, in particular through its ability to be bioconverted into L-selenomethionine, the natural source of selenium in human and animals.
A licensing agreement was signed to use NutraSelen® in Animal Nutrition.
Tetrahedron is a supplier of NutraSelen® (see below) as well as of L-(+)-ergothioneine and L-2-thiohistidine, which can be ordered on line (see below) according to our General Conditions of Sale ("Conditions générales de vente"). For request of quotation on larger quantities, please contact us.
