SDS of cas: 2682-49-7, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. In a article, 2682-49-7, molcular formula is C3H5NOS, introducing its new discovery.
The new title 4-thiazolidinone derivative, C 16 H 21 N 3 O 3 S, was obtained from the cyclization reaction of 4-methyl-3-thiosemicarbazone and dimethyl acetylenedicarboxylate (DMAD). The cyclohexylidene ring has an envelope conformation with the stereogenic centre C atom as the flap. Its mean plane makes a dihedral angle of 56.23(9) with the thiazolidine ring mean plane. In the crystal, molecules are linked by C – H?O hydrogen bonds forming chains propagating in the [001] direction. Within the chains there are offset pi-pi interactions between the thiazolidine rings of inversion-related molecules [centroid-centroid distance = 3.703(1)A]. The chains are linked by further C – H?O hydrogen bonds, forming slabs parallel to the ac plane.
