| Name | 4-Methylamino antipyrine |
| Description | 4-Methylamino antipyrine, an active metabolite of Metamizole, a pyrazolone non-steroidal anti-inflammatory drug (NSAID) that inhibits COX, possesses analgesic, antipyretic, and relatively weak anti-inflammatory properties. |
| In vitro | At room temperature and in an atmosphere with oxygen, Metamizole is spontaneously, nonenzymatically converted to 4-Methylamino antipyrine. Subsequently, the N-methyl side chain of 4-Methylamino antipyrine is oxidized to yield 4-formylaminoantipyrine, which is further converted to 4-aminoantipyrine [2]. |
| In vivo | Eight healthy male piglets are administered Metamizole (100 mg/kg) intramuscularly. 4-Methylamino antipyrine plasma concentrations are quantitatively detectable from 0.25 to 48 h. The average maximum concentration of 4-Methylamino antipyrine is 47.59 mg/mL. The average half-lives is 8.57 h for 4-Methylamino antipyrine [1]. |
| Storage | keep away from direct sunlight | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice. |
| Solubility Information | DMSO : 2.78 mg/mL (12.78 mM), Sonication is recommended.
