([18 f]fluoromisonidazole) remark: product consists of diastereomers of varying proportions without affecting product quality molar mass: 42546. Thus, it is important to assess hypoxia in tumors for estimating prognosis and selecting appropriate treatment procedures 18f-fluoromisonidazole positron emission tomography (18f-fmiso pet) has been widely used to visualize tumor hypoxia in a comprehensive and noninvasive way, both in the clinical and preclinical settings. Hypoxia in malignant tumors can affect the outcome of anti-cancer treatments malignant tumors are relatively resistant to chemotherapy and irradiative therapy because of their lack of oxygen, a potent radiosensitizer this is the reason for the multitude of efforts to develop methods and imaging techniques for measuring oxygen in tissues. 1410: fluoromisonidazole: 14100010: 10 mg per vial please inquire for customized filling and bulk quantities reference standard for [18 f]fmiso([18 f]fluoromisonidazole)molar mass: 18914 c 6 h 8 n 3 o 3 f [13551-89-8.
