Related Products of 18959-30-3, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 18959-30-3, Name is 4,5-Difluorophthalic Anhydride,introducing its new discovery.
Hydrolysis and bromination of phthalic anhydride in water gave a mixture of the monosodium salt of 4-bromophthalic acid. These were reacted with phenylacetylene under Sonogashira coupling reaction conditions in an aqueous medium. Acidification afforded 4-phenylethynylphthalic acid and then dehydration of this gave 4-phenylethynylphthalic anhydride in 76% overall yield. Compared with traditional synthetic methods, this method has the advantage of low cost, convenient manipulation and is environmentally friendly.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 18959-30-3, and how the biochemistry of the body works.Related Products of 18959-30-3
