The simplest form, methylamine, is typically made by the reaction of methanol and ammonia. Methylamines can be used to create intermediates for many agricultural chemicals, such as biocides, miticides and insecticides. Another agricultural use is making feed for chickens, turkeys and pigs.


Methylamine was first prepared in 1849 by Charles-Adolphe Wurtz via the hydrolysis of methyl isocyanate and related compounds. An example of this process includes the use of the Hofmann rearrangement, to yield methylamine from acetamide and bromine gas. In the laboratory, methylamine hydrochloride is readily prepared by various other methods.

Methamphetamine (contracted from N-methylamphetamine) is a potent central nervous system (CNS) stimulant that is mainly used as a recreational drug and less commonly as a second-line treatment for attention deficit hyperactivity disorder and obesity. Methamphetamine was discovered in 1893 and exists as two enantiomers: levo-methamphetamine and dextro-methamphetamine.


During the course of the series, methylamine is not synthesized by either Walter White or Jesse Pinkman, and thus the search for methylamine for use as a methamphetamine precursor is a large plot point throughout the series. For example, Walt and Jesse once stole methylamine from a warehouse, and, on a later date, from a freight train.
