The pyrazole ring is found in a number of drugs, such as
aminopyrine. Ring positions 1, 2, 3, 4, and 5 are the
positions to which R1–R5 are attached.

- Arguments 1, 2, 4:
- An argument of ``Q''
causes no action. All other argument values are used as
the respective substituent formulas R1, R2,
and R4.
- Argument 3:
- An argument of ``Q'' causes
no action. An argument of ``O'' puts an outside double
bond with an O in ring position 3. All other argument
values are used as the substituent formula R3
with a single bond.
- Argument 5:
- An argument of ``Q'' causes
no action. An argument of ``O'' puts an outside double
bond with an O in ring position 5. All other argument
values are used as the substituent formula R5
with a single bond.
- Arguments 6, 7, 8:
- An argument of ``D''
draws a second bond between ring positions 2 and 3,
ring positions 3 and 4, and ring positions 4 and 5,
respectively. All other argument values cause no action.
