Ethane-1,2-dithiol, also known as EDT, [1] is a colorless liquid with the formula C 2 H 4 2. It has a very characteristic odor which is compared by many people to rotten cabbage . It is a common building block in organic synthesis and an excellent ligand for metal ions.
In organic chemistry, a dithiol is a type of organosulfur compound with two thiol (−SH) functional groups.Their properties are generally similar to those of monothiols in terms of solubility, odor, and volatility.
Maximum concentrations in use that are generally recognised as safe (GRAS) is five parts per million (ppm) but typical uses are around 0.2 ppm. [1] It is supplied as a 1% solution in ethanol, due to its strong offensive smell. [2] In the diluted form with 4% ethyl acetate and ethanol the CAS number is 69382-62-3. [3]
Ethanethiol, commonly known as ethyl mercaptan, is an organosulfur compound with the formula CH 3 CH 2 SH. [5] It is a colorless liquid with a distinct odor. Abbreviated EtSH, it consists of an ethyl group (Et), CH 3 CH 2, attached to a thiol group, SH. Its structure parallels that of ethanol, but with sulfur in place of oxygen. The odor of ...

2-Mercaptoethanol (also β-mercaptoethanol, BME, 2BME, 2-ME or β-met) is the chemical compound with the formula HOCH 2 CH 2 SH. ME or βME, as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others).
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+ ) and calcium ions (Ca 2+ ), forming water-soluble complexes even at neutral pH.
