Question: What is Aurin freely soluble in that is also called alcohol?
Context: Diflucortolone valerate (also "Nerisone" cream/oily cream/ointment, "Neriderm" ointment, Japanese ジフルコルトロン (Jifurucorutoron ) is a corticosteroid rated Class 2 "potent" (100-150 times) in the New Zealand topical steroid system.  It is a white to creamy white crystalline powder.  It is practically insoluble in water, freely soluble in dichloromethane and in dioxan, sparingly soluble in ether and slightly soluble in methyl alcohol.  Chemically, it is a corticosteroid esterified with valeric acid.  It is commonly used topically in dermatology.  The brand name is Nerisone; its creams come in potencies of 0.1% and 0.3%. In the alcoholic beverages industry, congeners are substances, other than the desired type of alcohol, ethanol, produced during fermentation.  These substances include small amounts of chemicals such as methanol and other alcohols (known as fusel alcohols), acetone, acetaldehyde, esters, tannins, and aldehydes (e.g. furfural).  Congeners are responsible for most of the taste and aroma of distilled alcoholic beverages, and contribute to the taste of non-distilled drinks.  It has been suggested that these substances contribute to the symptoms of a hangover.  Congeners are also used by forensic toxicologists to determine what a person drank in a sub-discipline called alcohol congener analysis. Ethanol, also called alcohol, ethyl alcohol, and drinking alcohol, is a compound and simple alcohol with the chemical formula C2H5OH .  Its formula can be written also as CH3 −CH2 −OH or C2H5 −OH (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH.  Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor.  It is used as a drug and is the principal type of alcohol found in alcoholic drinks. Furfuryl alcohol, also called 2-furylmethanol or 2-furancarbinol, is an organic compound containing a furan substituted with a hydroxymethyl group.  It is a clear colorless liquid when pure, but becomes amber colored upon prolonged standing.  It possesses a faint odor of burning and a bitter taste.  It is miscible with but unstable in water.  It is soluble in common organic solvents. Upon treatment with acids, heat and/or catalysts, furfuryl alcohol can be made to polymerize into a resin, poly(furfuryl alcohol). Murexide (NHCHNO, or CHNO·NH), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid.  It may be prepared by heating alloxantin in ammonia gas to 100 °C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide.  W. N. Hartley found considerable difficulty in obtaining specimens of murexide sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for murexide.  In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours.  The solution is then filtered from the precipitated murexide, which is washed with absolute alcohol and dried.  The salt obtained in this way is in the anhydrous state.  It may also be prepared by digesting alloxan with alcoholic ammonia at about 78 °C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of murexide. 1-Hexacosanol is a saturated primary fatty alcohol with a carbon chain length of 26 that is a white waxy solid at room temperature.  It is freely soluble in chloroform and insoluble in water.  It occurs naturally in the epicuticular wax and plant cuticle of many plant species. Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of CHOH, which occurs in five isomeric structures, from a straight-chain primary alcohol to a branched-chain tertiary alcohol; all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, n"-BuOH, and i"-BuOH).  These are "n"-butanol, 2 stereoisomers of 2-butanol, "tert"-butanol, and isobutanol.  Butanol is primarily used as a solvent, as an intermediate in chemical synthesis, and as a fuel.  It is sometimes also called biobutanol when produced biologically. Designated Public Place Orders (DPPOs) give police officers discretionary powers to require a person to stop drinking and confiscate alcohol or containers of alcohol from people they believe are consuming or about to consume alcohol in public places where the order is in effect.  In the London Borough of Southwark, DPPOs are also called Alcohol Control Areas (ACAs), while in the London borough of Hammersmith and Fulham, they are called Controlled Drinking Areas (CDAs) or Controlled Drinking Zones (CDZs).  Failure to comply with alcohol restrictions in DPPOs can result in arrest and/or a fine of up to £500.  DPPOs are implemented by local councils in order to address alcohol-related crime and disorder in public places.  s of June 2009 712 DPPOs have implemented by local authorities since Section 13 of the Police and Criminal Justice Act 2001 gave councils the power to do so where they were satisfied that areas were suffering from alcohol-related crime and disorder.  A common impact of enforcement of DPPO powers is displacement of street drinking to nearby areas. Aurin (C.I. 43800), sometimes named rosolic acid or corallin is an organic compound, forming yellowish or deep-red crystals with greenish metallic luster.  It is practically insoluble in water, freely soluble in alcohol.  It is soluble in strong acids to form yellow solution, or in aqueous alkalis to form carmine red solutions.  Due to this behaviour it can be used as pH indicator with pH transition range 5.0 - 6.8.  It used as intermediate in manufacturing of dyes. Phosphomolybdic acid, also known as dodeca molybdophosphoric acid or PMA is a component of Masson's trichrome stain.  It is a yellow-green compound, freely soluble in water and polar organic solvents such as ethanol.  It is used as a reagent in thin layer chromatography for staining phenolics, hydrocarbon waxes, alkaloids and steroids.
