It is a form of Vitamin D and it is currently produced and marketed by Vitamin Derivatives. It is very sensitive to UV radiation and will rapidly, but reversibly, break down to form supra-sterols. 1-Hydroxycholecalciferol with cas registry number of 57651-82-8 can be used as an feed additive for the prevention of tibial dyschondroplasia and phytate phosphorus utilization .
