Mercaptoacetic acid Usage And Synthesis |
|
Chemical Properties |
Colorless Liquid |
|
Usage |
Thioglycolic Acid is an organic compound containing both a thiol and a carboxylic acid. Thioglycolic Acid is a precursor to ammonium thioglycolate, a chemical used for permanents. Thioglycolic Acid is used in organic synthesis as a nucleophile in thioglycolysis reactions and is used as a S transfer agent for sulfonyl chloride synthesis. |
|
General Description |
A colorless liquid with an unpleasant odor. Density 1.325 g / cm3. Used to make permanent wave solutions and depilatories. Corrosive to metals and tissue. |
|
Air & Water Reactions |
Readily oxidized by air. Water soluble. |
|
Reactivity Profile |
Mercaptoacetic acid is readily oxidized by air . Reacts readily with other oxidizing agents as well in reactions that may generate toxic gases. Incompatible with diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials may generate heat and toxic and flammable gases. May react with acids to liberate hydrogen sulfide. Neutralizes bases in exothermic reactions. Reacts with cyanides, sulfites, nitrites, thiosulfates to generate flammable and toxic gases and heat. Reacts with carbonates and bicarbonates. |
|
Health Hazard |
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. |
|
Fire Hazard |
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. |
