Potassium phosphate monobasic (monopotassium orthophosphate) is a water soluble inorganic salt. Its standard enthalpy of formation has been reported to be -376.1kcalmol-1.[5] It acts a starting material in the synthesis of potassium metaphosphate...

4-Androstenedione, commonly known as Androstenedione, is an endogenous androgen steroid hormone. 4-Androstenedione functions as an intermediate in the biosynthesis of testosterone, estradiol and estrone. Recent studies indicate that 4-Androstenedione is involved in aromatase inhibitors induce painfu..

5-α-androst-16-en-3-α-ol (androstenol) is an androgen believed to act as a pheromone. Androstenol has been used in a study to develop a combined gas chromatography/thermal conversion/isotope ratio mass spectrometry (GC/TC/IRMS) method for D/H ratio determination of endogenous urinary steroids...

5α-Androstan-17β-ol-3-one, also referred to as androstanolone or dihydrotestosterone, is an anabolic steroid. Testosterone secreted by the testis is converted to dihydrotestosterone in the target tissues where it appears to mediate many of the biological actions of testosterone, including the develo..
