Organic Salts

1,6-Hexanediol (HOCH₂(CH₂)₄CH₂OH) is a colorless crystalline solid that melts at 42 °C and boils at 250 °C.^[2] It is soluble in water and is hygroscopic. 1,6-Hexanediol is prepared industrially by the hydrogenation of adipic acid. Laboratory synthesis can be done by reduction of adipic acid with lithium aluminium hydride, however, since it is cheaply and commercially available, it is usually not synthesized in the laboratory.

Piperidine is an organic compound with the molecular formula (CH₂)₅NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH₂–) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines.^[4]The name comes from the genus name Piper, which is the Latin word for pepper.^[5] Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids.

Formamide, also known as methanamide, is an amide derived from formic acid. It is a clear liquid which is miscible with water and has an ammonia-like odor. It is chemical feedstock for the manufacture of sulfa drugs, other pharmaceuticals, herbicides, pesticides and the manufacture of hydrocyanic acid. It has been used as a softener for paper and fiber
