Description and Uses

Cysteamine, also known as 2-aminoethanethiol, is a chemical compound with the formula HSCH₂CH₂NH₂. It is the simplest stable aminothiol and a degradation product of the amino acid cysteine. It is often used as the hydrochloride salt, HSCH2CH2NH3Cl. The comparatively high melting point of cysteamine (95-97 °C), indicates that exists in a salt form.

2-Aminoethanethiol is used in preparation method of fluorescence quenching array sensor based on cadmium telluride quantum dots and application in qualitative discrimination and quantitative analysis of organic acids.
