Aminoacetonitrile Hydrochloride丨CAS 6011-14-9

Aminoacetonitrile hydrochloride (CAS 6011-14-9) is a small, bifunctional reagent widely used as a building block in organic and medicinal chemistry. It's employed to introduce an aminomethyl–nitrile motif into molecules, enabling access to -amino acids (via nitrile hydrolysis), aminomethylated heterocycles, and diverse nitrogen-containing scaffolds. Typical transformations include reductive amination, nucleophilic substitution at the aminomethyl position, Strecker-type or related condensations to prepare -amino nitriles, and subsequent conversion of the nitrile into amides, acids or amidines. Because of these pathways it finds use in synthesis of pharmaceutical intermediates, agrochemical precursors, and fine chemicals, and also in method development and library synthesis where introducing a one-carbon nitrogen fragment is useful.

The main benefit of the hydrochloride salt is practical: as a crystalline, non-volatile solid it's easier and safer to handle and store than the free base, and it often shows good solubility in polar solvents used for standard organic transformations. Functionally, the combination of a primary amine and a nitrile in one reagent gives high synthetic flexibility - you can derivatize the amine (acylation, alkylation, coupling) while separately transforming the nitrile (hydrolysis, reduction, or cyclization), enabling stepwise construction of complex molecules from a single, compact fragment. This dual reactivity shortens routes, reduces protecting-group gymnastics, and supports rapid SAR (structure–activity relationship) exploration in medicinal chemistry.
