Analysis of the metabolite markers of azathioprine (AZA) and mercaptopurine (6-MP), including 6-methyl-mercaptopurine ribonucleotides (6-MMRP) and 6-thioguanine nucleotides (6-TGN), is considered investigational.
Though the temperature of the inner core of the Earth is about 5700 degrees, (about as hot as the surface of the Sun) the pressure is also very high, about 3.3 - 3.6 million aâ¦tmospheres. At these pressures the material is solid, as has been confirmed in lab tests.
All that pressure keeps the metal in the inner core in solid form, despite its extremely high temperature. Recent scientific studies lead experts to believe that Earth's inner core is approximately 10,800Âº F â or about the same temperature as the surface of the Sun!
