Further aspects relate to pharmaceutical compositions, therapeutic uses and process for preparing compounds of formulae 1a and 1b
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 2081-44-9 is helpful to your research., Reference of 2081-44-9
