One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, COA of Formula: C8H9N3O2, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 41959-35-7, Name is 6-Nitro-1,2,3,4-tetrahydroquinoxaline, molecular formula is C8H9N3O2
Hair dye compositions and certain 1,2,3,4-tetrahydronitroquinoxalines useful therein
The invention relates to the use of compounds corresponding to formula (I) STR1 in which one of the substituents R1 or R2 is a nitro group while the other is hydrogen, halogen, an amino group, a mono- or dialkylamino group containing C1-4 alkyl groups, a C1-4 alkyl or alkoxy group, R3 and R4 independently of one another represent hydrogen or a C1-4 alkyl group, A is a >CHR6 – or a >C=O- group, where R6 is hydrogen or a C1-4 alkyl group, and R5 is hydrogen or a C1-4 alkyl group, or salts thereof as substantive dyes in hair-dyeing compositions. When the substituent groups in formula I represent one of the combinations I-IV shown in the table below, the compounds are novel and are useful in hair-dyeing compositions. ______________________________________R1 R2 R3 R4 R5 A______________________________________I: H NO2 H CH3 H CH2II: H NO2 CH3 CH3 H CH2III: NH2 NO2 H H H CH2IV: H NO2 H H CH3 CH2.______________________________________
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C8H9N3O2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 41959-35-7, in my other articles.
