Abstract
Official abstract text for this publication.
Provided are a method for purifying mitomycin C, comprising a step of recrystallizing crude mitomycin C crystals using a high-purity methanol; mitomycin C obtainable by the method; and the like.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for purifying mitomycin C, comprising a step of recrystallizing crude mitomycin C crystals using a high-purity methanol. 2. The method according to claim 1 , wherein the high-purity methanol has a purity of 99.00 to 99.99%. 3. The method according to claim 1 , wherein the high-purity methanol has a purity of 99.50 to 99.99%. 4. The method according to claim 1 , wherein the high-purity methanol has a total metal concentration of 0.01 to 300 ppb. 5. The method according to claim 1 , wherein the high-purity methanol has a total metal concentration of 0.01 to 100 ppb. 6. The method according to claim 1 , wherein the high-purity methanol has a zinc concentration of 0.01 to 100 ppb. 7. The method according to claim 1 , wherein the high-purity methanol has a zinc concentration of 0.01 to 10 ppb.
