Use

2-AMINOETHANETHIOL is the 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 iswhite powder 2-AMINOETHANETHIOL is an amine that consists of an ethane skeleton substituted with a thiol group at C-1 and an amino group at C-2. 2-AMINOETHANETHIOL is used as the hydrochloride salt, as it readily oxidizes to the corresponding disulfide, in the presence of air. The amine portion of the molecule serves as a catalyst for this reaction. 4 HSCH2CH2NH2 + O2 → 2 NH2CH2CH2SSCH2CH2NH2 + 2 H2O. ANTIOXIDANTS is used to preserve food by retarding deterioration, rancidity, or discoloration due to oxidation. The most commonly used antioxidant formulations contain combinations of BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), and propyl gallate. Natural such as tocopherols and guaiac gum usually lack the potency of BHA, BHT, and propyl gallate combinations. Are effective at low concentrations, that is, 0.02% or less.
