Naphthalene's minimum odor threshold is 0.084 ppm for humans. [42] Mothballs and other products containing naphthalene have been banned within the EU since 2008. [43] [44] In China, the use of naphthalene in mothballs is forbidden. [45] Danger to human health and the common use of natural camphor are cited as reasons for the ban.
Alcohol has been used as an antiseptic as early as 1363, with evidence to support its use becoming available in the late 1800s. [ 32 ] At times and places of poor public sanitation (such as medieval Europe ), the consumption of alcoholic drinks was a way of avoiding water-borne diseases such as cholera .
It is a colorless, crystal-like solid, but can also appear yellow. Phenanthrene is used to make dyes, plastics, pesticides, explosives, and drugs. It has also been used to make bile acids, cholesterol and steroids. [3] Phenanthrene occurs naturally and also is a man-made chemical.
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH.It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring.
Another example is aromatic rings, where a phenyl-C 6 H 5 ring can often be replaced by a different aromatic ring such as thiophene or naphthalene which may improve efficacy, change specificity of binding or reduce metabolically labile sites on the molecule, resulting in better pharmacokinetic properties. Alloxanthine is an inhibitor of ...
Naphthalene-2-thiol. Identifiers CAS Number. 91-60-1; 3D model . ... It can be used as a flavouring agent and has been described as having an “artichoke ...
It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive. Both isomers are soluble in simple alcohols, ethers, and chloroform. 2-Naphthol is a widely used intermediate for the production of dyes and other compounds.
Rubbing alcohol, also known as surgical spirit in some regions, refers to a group of denatured alcohols commonly used as topical antiseptics. These solutions are primarily composed of either isopropyl alcohol (isopropanol) or ethanol , with isopropyl alcohol being the more widely available formulation.
