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.
The temperature of the inner core can be estimated using experimental and theoretical constraints on the melting temperature of impure iron at the pressure (about 330 GPa) of the inner core boundary, yielding estimates of 5,700 K (5,430 Â°C; 9,800 Â°F).
