Trivedi, A. R. published the artcileA facile synthesis of pyrazolo[3,4-d]pyrimidines, Product Details of C10H9ClN2O, the publication is Indian Journal of Heterocyclic Chemistry (2008), 17(4), 385-386, database is CAplus.
A new series of the pyrazolo[3,4-d]pyrimidines were prepared by one-pot reaction of 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde, 1-(aryl)-3-methyl-1H-pyrazol-5-(4H)-ones and thiourea. Compounds were evaluated for their antimicrobial activity. Some of the compounds showed interesting antimicrobial activity as compared to the standard drugs.
Indian Journal of Heterocyclic Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C8H5F3N4, Product Details of C10H9ClN2O.
