Where is the good Temozolomide

Where is the good Temozolomide? Many people don't know much about it, and here's the introduction:

The primary agent for tamoxazolamine is white or light brown/pale pink powder, and the relative molecular mass is 194.15. PH7 easy decomposition, from methylene chloride crystallization, melting point 212 ℃ (decomposition). UV maximum absorption (95% ethanol) : 327nm. It is slightly soluble in dimethylsulfone, which is dissolved in water, dissolves in methanol and is almost insoluble in ethanol, and is dissolved in acetic acid. Clinical use of the active metabolite MTIC, which can be spontaneously and rapidly decomposed in the body, produces an anti-tumor effect.
