Pilocarpine properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.
| Property | Value | Conditions | Source |
|---|---|---|---|
| Boiling point | 260 °C (500 °F) | at 5 mmHg (reduced pressure), PARTIAL CONVERSION TO ISOPILOCARPINE | HSDB |
| Melting point | 34 °C (93.2 °F) | HSDB | |
| 200 °C (392 °F) | range, midpoint shown | DrugBank | |
| Solubility | FREELY SOL IN ETHANOL; INSOL IN DIETHYL ETHER | HCL | HSDB |
| SOL IN WATER, ALC, CHLOROFORM; SPARINGLY SOL IN ETHER, BENZENE; ALMOST INSOL IN PETROLEUM ETHER | HSDB | ||
| SOL IN ETHANOL, DIETHYL ETHER | HSDB |
