3,3,5-Trimethylcyclohexanol is a precursor to the vasodilator cyclandelate, the sunscreen component homosalate and the VP nerve agent. [ 1 ] [ 2 ] It can be synthesized by hydrogenation of isophorone . [ 3 ]
It can be prepared as a yellow sublimate at 1000 °C by reacting GeO 2 with Ge metal. The yellow sublimate turns brown on heating to 650 °C. [1] GeO is not well characterised. [1] It is amphoteric, dissolving in acids to form germanium(II) salts and in alkali to form "trihydroxogermanates" or "germanites" containing the Ge(OH) 3 − ion. [2]
Unit fractions can also be expressed using negative exponents, as in 2 −1, which represents 1/2, and 2 −2, which represents 1/(2 2) or 1/4. A dyadic fraction is a common fraction in which the denominator is a power of two , e.g. 1 / 8 = 1 / 2 3 .
A 2004 scientific paper suggested that ketoconazole 2% shampoo can disrupt the DHT pathway, potentially inhibiting DHT production or stopping the hormone from binding to androgen receptors.
In mathematics, the binary icosahedral group 2I or 2,3,5 [1] is a certain nonabelian group of order 120. It is an extension of the icosahedral group I or (2,3,5) of order 60 by the cyclic group of order 2, and is the preimage of the icosahedral group under the 2:1 covering homomorphism

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
