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 outer core is around 4400 degrees celsius. The depth of the outer core is 2, 890. This is one of the three layers that is putting pressure on the inner core. It is the second hottest layer, because it is the layer above the inner core, and it is the second farthest from the surface of the earth.
