Methyl hydrogen peroxide

However in low NOx conditions peroxy radicals primarily react through self and cross peroxy-peroxy reactions to form methyl hydrogen peroxide (CH3OOH) and hydrogen peroxide (H202). H02 is also recycled back to OH through the reaction with 03 (Reaction 9). 

The methyl hydrogen peroxide contributes to OH loss via Reactions (12) and (13) to form CH302 and HCHO. 

In spite of these anomalies, the idea of a complex remained a working hypothesis, particularly since kinetic studies failed to reveal any intermediate (s) preceding Compound I formation 144, 157) and since the interaction of bacterial catalase with methyl hydrogen peroxide could be expressed in terms of an equilibrium reaction 158). The latter proposition...

Therefore, ki/k-i 8 X 10 S provided that as in the reactions of catalase with methyl hydrogen peroxide (Table VIII) or with formic acid (37), ki 10 sec . Further, since even at 2 mM MeOH, the kinetics of Compound I reduction by methanol obey the second-order rate law (143), it follows that fc i//fci > 20 mM. Hence, k-i > 2 X 10 sec and kt > 16 sec. ... 

The reagent M0O5.HMPA, known as MoOPH , brings about addition of the elements of methyl hydrogen peroxide to an A-acyl-indole, and these adducts in turn, can be utilised one application is to induce loss of methanol, and thus the overall transformation of an indole into an indoxyl (20.13.2). ... 

Chance (91) has also shown that methyl hydrogen peroxide can act as a substrate for both catalase and peroxidase, but not as a donor reacting with the catalase MeOOH complex. Smith (323a), working in Chance s laboratory, has recently used MeOOH to measure the amount of peroxidase in bakers yeast in the presence of catalase.
