Application of 21169-71-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 21169-71-1, Isoxazole-5-carboxylic acid, introducing its new discovery.
A compound of the formula (I): STR1 or pharmaceutical acceptable salts thereof wherein X is NR1, S(O)g, or O; R1 is H, C1-6 alkyl optionally substituted with one or more OH, CN, or halo, or R1 is –(CH2)h — aryl, –COR1–1, –COOR1-2, –CO–(CH2)h –COR1–1, C1-6 alkyl sulfonyl, –SO2 –(CH2)h –aryl, or –(CO)i –Het; R2 is H, C1-6 alkyl, –(CH2)h –aryl, or halo; R3 and R4 are the same or different and are H or halo; R5 is H, C1-12 alkyl optionally substituted with one or more halo, C3-12 cycloalkyl, C1-6 alkoxy. The compounds are useful antimicrobial agents.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 21169-71-1. In my other articles, you can also check out more blogs about 21169-71-1
