A fluorine-containing vitamin D2 derivative represented by the following formula
wherein R1 represents a methyl or trifluoromethyl group, and R2 represents a trifluoromethyl group when R1 is a methyl group, and a hydrogen atom or a methyl group when R1 is a trifluoromethyl group. This compound is useful for the prevention or treatment of caloium pathobolism or osteoporoeis.

AbstractThe 2‐aryl‐4‐bromo‐5‐trifluoromethylpyrrole‐3‐carbonitriles represent a new class of insect control agents. The high insectidical activity observed in this series prompted us to investigate the preparation of regioisomeric arylhalotrifluoromethylpyrrole carbonitriles. The synthesis and biological activity of eight of the twelve possible regioisomers are described and discussed.

The present invention is in the field of household cleaning, for example laundry products and methods. The invention is directed to the use of indicator materials, such as fluorescent indicator materials, for detecting or visualizing organic laundry soils, particularly those that tend to be invisible to the naked eye, such as sebum, perspiration, biological soils, odor-causing soils/stains and tannins. In addition, the present invention is directed to methods of using indicator materials, such as fluorescent indicator materials, to detect such soils on fabrics, and to determine and demonstrate the cleaning efficacy of a laundry product.
