  • 25-hydroxycholecalciferol monohydrate crystal, preparation method therefor and microemulsion using same
    Patent number: 11584713
    Abstract: A 25-hydroxycholecalciferol monohydrate crystal, a preparation method thereof, and a microemulsion using the 25-hydroxycholecalciferol monohydrate crystal. The X-ray powder diffraction spectrum of the 25-hydroxycholecalciferol monohydrate crystal of the present disclosure shows characteristic peaks at 2? of 10.035°, 11.623°, 14.631°, 15.054°, 15.551°, 16.471°, 17.198°, 19.002°, 19.628°, 20.109°, 21.886°, 23.113°, 23.661°, 24.701°, 25.220°, 25.440°, and 28.527°. The 25-hydroxycholecalciferol monohydrate crystal can effectively enhance the stability of 25-hydroxycholecalciferol, and is more beneficial to the production and storage of related preparations, and thus biological characteristics of 25-hydroxycholecalciferol can be effectively utilized.
