Chemistry is traditionally divided into organic and inorganic chemistry. name: Ethyl 5-chloro-6-fluoro-1H-indole-2-carboxylate. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 473257-60-2
The invention concerns anti-tumour agents of formula (I) wherein each of R1 ,R2 and R3 has the meanings defined in the specification including hydrogen, (1-4C)alkyl, (3-4)alkenyl, (3-4C)alkynyl, amino, (1-4C)alkylamino and (1-4C)alkoxy; each of R4 and R5 is (1-4C)alkyl; each of R6 and R7 is hydrogen or (1-4C)alkyl; X is oxygen; m is 1 or 2 and each R8 is as defined in the specification; each of Y1 and Y2 is halogeno, (1-4C)alkanesulphonyloxy, benzenesulphonyloxy or phenyl-(1-4C)akanesulphonyloxy; or a pharmaceutically-acceptable salt thereof; provided that at least one of R1, R2 and R3 is other than hydrogen; a process for preparation, pharmaceutical compositions containing them and their use in the production of an anti-proliferative effect
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: Ethyl 5-chloro-6-fluoro-1H-indole-2-carboxylate, you can also check out more blogs about473257-60-2
