Usage

Description

DMPS, also known as 2,3-dimercapto-1-propanesulfonic acid, is an alkanesulfonic acid with sulfanyl groups at positions 2 and 3. It is a chelating agent that has the ability to bind with heavy metals, making it useful in various applications.

Uses

Used in Medical Applications:
DMPS is used as a chelating agent for the treatment of heavy metal poisoning. It helps to remove toxic heavy metals such as lead, arsenic, and mercury from the body by forming stable, water-soluble complexes that can be excreted through urine.
Used in Environmental Applications:
DMPS is used as a heavy metal detoxifier in environmental remediation processes. It can be applied to contaminated soil or water to bind and remove heavy metals, reducing their toxicity and facilitating their safe disposal.
Used in Analytical Chemistry:
DMPS is used as a reagent in analytical chemistry for the detection and quantification of heavy metals. Its chelating properties allow for the selective binding and extraction of heavy metal ions, enabling their analysis and identification.
Used in Pharmaceutical Industry:
DMPS is used as a component in the development of drugs for the treatment of heavy metal poisoning. Its ability to bind and remove heavy metals makes it a valuable tool in the creation of therapeutic agents for metal toxicity.

Method for preparing sodium 2,3-dimercapto-1-propanesulfonate

The invention belongs to the technical field of drug synthesis, and in particular relates to a method for preparing sodium 2,3-dimercapto-1-propanesulfonate. With sodium allysulfonate used as a starting material and through a bromination reaction, a sulfhydrylation reaction, a lead salt reaction and a lead removal reaction, high-content sodium 2,3-dimercapto-1-propanesulfonate is obtained by refinement. The total yield is 23.2% and above; especially when zinc dust reduction step is added after hydrolysis, the yield can be greatly increased, the total yield can reach 35-41.5%, and the refined sodium 2,3-dimercapto-1-propanesulfonate content reaches 99% and above. Ethanethioic acid potassium salt is used as a sulphurizing agent and then is hydrolyzed under strong acid conditions, and dilutesulfuric acid is used for lead removal after lead formation. During the whole reaction and treatment process, toxic gas hydrogen sulfide which affects the environment is prevented from being used or generated. Thereby, working conditions are improved, emission of three wastes is reduced, and production efficiency is enhanced.
