You could be based in a university, combining chemical research with teaching, HPLC of Formula: C3H5NOS, in a pharmaceutical company, working on developing and trialing new drugs; or in a public-sector research center, helping to ensure national healthcare provision keeps pace with new discoveries. 2682-49-7, Name is Thiazolidin-2-one, molecular formula is C3H5NOS. In a Patent，once mentioned of 2682-49-7
3-[4-1-substituted-4-piperazinyl)butyl]-4-thiazolidinone compounds which are useful as antipsychotic, analgesic, anticonvulsant and anxiolytic agents.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2682-49-7 is helpful to your research. HPLC of Formula: C3H5NOS
