5-Chloro-3-methyl-4-nitro pyrazole

In pyrazoles the two most important effects are produced by nitro groups and by quaternization (Section 4.02.3.1.7). Both enhance considerably the reactivity of a second substituent, for example, that of a methyl group towards aldehydes or of a chloro substituent towards amines. 

The nitration (fuming nitric acid) of 5-chloro-3-methyl-l-phenylpyrazole is reported to give a mononitro product (presumably the 4-nitrophenyl derivative) and a dinitro product 5-chloro-3-methyI-4-nitro-l-(4-nitro-phenyl)-pyrazole (1900CB2595 11LA329).

Chloro-3-methyl-4-nitro-lH-pyrazole (Release) has no auxin-, gib-berellin-, or cytokinin-like activity, yet it is an ejffective abscission agent. At the present, there is no evidence to indicate that Release retards auxin, gibberellin, or cytokinin activity. It does stimulate and enhance the tissue production of ethylene (105). Release is fairly stable, and there is no indication that it is degraded by the tissue to ethylene per se (106).
