Product Information
Description: Temozolomide acid is a carboxylic acid derivative of Temozolomide. Temozolomide is a DNA alkylating agent, methylating the guanine and adenine bases of DNA, causing breaks in DNA double strand, cell cycle arrest, and eventually cell death. Temozolomide acid has an activity similar to the parent compound Temozolomide with the same anticancer activity.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
