Organic Halides

Zinc bromide dihydrate is a crystalline compound that is used as a catalyst for the conversion of metalloporphyrins to hydroporphyrins. This process is used in the production of vitamin B12. Zinc bromide dihydrate can also be used to inhibit the function of ion pumps, which are proteins that pump ions across membranes. The inhibition of these pumps may lead to a decrease in intracellular calcium levels and an increase in free radicals.
Zinc bromide dihydrate has been shown to react with chlorophylls, vinylated heterostructures, and polyvinyl nonmetals. These reactions produce morphology changes in zinc bromide dihydrate crystals

Pentafluoropropionic acid is a glycol ether that is used in the preparation of coumarin derivatives. It reacts with sodium carbonate and trifluoroacetic acid to form the corresponding acyl chloride, which then reacts with nitrogen atoms (e.g., ammonia) to form an amide or urea derivative. Pentafluoropropionic acid also reacts with hydrogen fluoride to form pentafluoropropane and hydrogen fluoride gas, which can be used as a propellant for aerosol sprays. Pentafluoropropionic acid binds to toll-like receptors on cancer cells and human serum, inhibiting their ability to synthesize DNA. The compound has been shown to inhibit tumor growth in mice by blocking the formation of cancer tissues.

Potassium hexafluorophosphate is a chemical compound that is used as an antimicrobial agent in the laboratory. It reacts with hydroxyl groups on various surfaces to form potassium hexafluorophosphate and water. The reaction solution can be used to disinfect equipment and surfaces, and is stable at room temperature. Potassium hexafluorophosphate has been shown to have biological properties such as inhibiting the growth of bacteria and fungi, but not viruses. This chemical compound has been shown to be effective against E. coli, Klebsiella pneumoniae, Staphylococcus aureus, Proteus vulgaris, Bacillus subtilis, Pseudomonas aeruginosa, Aspergillus niger, Candida albicans, or Saccharomyces cerevisiae.
