A deadly poison by ingestion, subcutaneous, and intravenous routes. Experimental teratogenic and reproductive effects. When heated to decomposition it emits acrid smoke and fumes.

 1-Hydroxycholecalciferol with cas registry number of 57651-82-8 is also known as (1S,3Z)-3-[(2E)-2-{(1R,3aS,7aR)-1-[(1R)-1,5-Dimethylhexyl]-7a-methyloctahydro-4H-inden-4-yliden}ethyliden]-4-methylidencyclohexanol ; (1S,3Z)-3-[(2E)-2-{(1R,3aS,7aR)-1-[(1R)-1,5-dimethylhexyl]-7a-methyloctahydro-4H-inden-4-ylidene}ethylidene]-4-methylidenecyclohexanol ; (1S,3Z)-3-[(2E)-2-{(1R,3aS,7aR)-1-[(1R)-1,5-diméthylhexyl]-7a-méthyloctahydro-4H-indén-4-ylidène}éthylidène]-4-méthylidènecyclohexanol ; (1S,3Z)-4-Methylene-3-[(2E)-2-{(1R,3aS,7aR)-7a-methyl-1-[(2R)-6-methyl-2-heptanyl]octahydro-4H-inden-4-ylidene}ethylidene]cyclohexanol ; (3b,5Z,7E)-9,10-Secocholesta-5,7,10(19)-trien-3-ol ; (3beta,Z,7E)-9,10-Secocholesta-5,7,10(19)-trien-3-ol ; (3S,5Z,7E)-9,10-Secocholesta-5,7,10-trien-3-ol  ; (3S,5Z,7E)-9,10-Secocholesta-5,7,10-trién-3-ol ; 9,10-Secocholesta-5,7,10(19)-trien-3b-ol ; 9,10-Secocholesta-5,7,10(19)-trien-3-ol, (3beta,5Z,7E)- . 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 .
