MeIQx, also known as 8-Methyl-IQX, is a synthetic, pale orange to brown crystalline solid that is soluble in dimethylsulfoxide and methanol. It is produced in small quantities for research purposes. 2-Amino-3,8-dimethylimidazo[4,5-f]quinoxaline is formed naturally during the cooking of muscle-derived foods (meat and fish). Levels of this chemical produced in this manner are dependent on cooking temperature, cooking time and method of cooking (direct or indirect). It is one of the most abundant heterocyclic amines in a typical Western diet. 2-Amino-3,8-dimethylimidazo[4,5-f]quinoxaline has also been detected in processed food flavorings, beer, wine, and cigarette smoke. It is reasonably anticipated to be a human carcinogen.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
