Irritancy isopropyl groups

The amines are a group of compounds with the general formula R-NHj, and all the common amines are hazardous. As a class the amines pose more than one hazard, being flammable, toxic, and, in some cases, corrosive. The amines are an analogous series of compounds and follow the naming pattern of the alkyl halides and the alcohols that is, the simplest amine is methyl amine, with the molecular formula of CH NHj. Methyl amine is a colorless gas with an ammonia-like odor and an ignition temperature of 806°F. It is a tissue irritant and toxic, and it is used as an intermediate in the manufacture of many chemicals. Ethyl amine is next in the series, followed by propyl amine, isopropyl amine, butyl amine and its isomers, and so on. 

Propanol undergoes reactions characteristic of a secondary —OH group. Oxidation is highly exothermic (43 kcal/mol) but occurs above 300° C (572°F), forming acetone. It reacts with acid chlorides, chlorine, and phosphorus chloride to produce chloroacetones (toxic). It loses water molecules over acid catalysts such as alumina or sulfuric acid, to form diisopropyl ether (flammable) and propylene (flammable, forms an explosive mixture with air). It forms isopropyl acetate (mucous membrane irritant, narcotic) with acetic acid. Treatment with nitrosyl chloride or with sodium... 

A hydroxyl group (-0H) on benzene yields the compound phenol, CgHjOH. The -ol suffix on phenol indicates that phenol is an alcohol. Phenol was one of the first chemicals to be used as a disinfectant. In fact, its use dates to 1865. Phenol can be pretty irritating to tissues, however, so it is no longer used for that purpose. However, other alcohols, particular rubbing alcohol (isopropyl alcohol) are still used today as disinfectants without the side effects of phenol.
