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 21725-69-9 is helpful to your research. SDS of cas: 21725-69-9
Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In a patent, 21725-69-9, molecular formula is C7H5NO2, introducing its new discovery. SDS of cas: 21725-69-9
BENZISOXAZOLES
The present invention concerns the compounds of formula (I), the N-oxide forms, the pharmaceutically acceptable addition salts and the stereochemically isomeric forms thereof, wherein m represents an integer from 1 to 3; X represents amino, hydroxy, -oxo or -Z-R1; Y is absent when X represents -Z-R1 and -(C=O)-R6 when X represents oxo; Z represents carbonyl, -oxy-carbonyl- or -NR 5-carbonyl-; R1 represents C1-4alkyl, Ar1, Ar1-C1-4a1ky1-, -NR3R4 or -Het1; R2 represents hydrogen, halo, nitro, hydroxycarbonyl-, C1-4alkyloxy or C1-4alkyl; R3 and R4 are each independently selected from hydrogen, Ar3 or C1-4alkyl; R5 represents hydrogen, C1-4alkylcarbonyl- or Ar4-carbonyl-; R6 represents a substituent selected from the group consisting of C1.4alkyl, Ar5, Ar6-C1-4alkyl- or NR7R8; R7 and R8 are each independently selected from hydrogen, Het4 or C1-4alkyl; Het1 represents a heterocycle selected from oxazolyl, isoxazolyl, imidazolyl or pyrazolyl wherein said heterocycle is optionally substituted with one, two or three substituents selected from the group consisting of amino, C1-4alkyl, hydroxy-C1-4alkyl, phenyl, phenyl-C1-4alkyl- and phenyl substituted with one or more halo substituents; Het4 represents a heterocycle selected from oxazolyl or isoxazolyl, wherein said heterocycle is optionally substituted with one or more substituents selected from the group consisting of amino, C1-4alkyl, hydroxy-C1-4alkyl-, phenyl, phenyl-Cl-4alkyl and phenyl substituted with one or more halo substituents; and Ar1, Ar2, Ar3, Ar4, Ar5 or Ar6 each independently represents phenyl optionally substituted one or where possible two or more substituents selected from halo, nitro, C1-4alkyl, hydroxy or C1-4alkyloxy-.
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 21725-69-9 is helpful to your research. SDS of cas: 21725-69-9
