Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view.2081-44-9, Name is Tetrahydro-2H-pyran-4-ol, molecular formula is C5H10O2. In a Patent，once mentioned of 2081-44-9, Reference of 2081-44-9
The present invention provides benzo[b]thiophenes of Formula (I) wherein R1, R2, R3, and L have any of the values defined therefor in the specification, and pharmaceutically acceptable salts thereof, that are useful as agents in the treatment of diseases and conditions, including inflammatory diseases, cardiovascular diseases, and cancers. Also provided are pharmaceutical compositions comprising one or more compounds of Formula I.
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
