Description
Dimercaptosuccinic acid, also known as 2,3-dimercaptosuccinic acid (DMSA), is a chelating agent with two thiol (-SH) groups that can bind to heavy metal ions. It is a synthetic compound with a molecular structure consisting of a succinic acid backbone with two mercapto (-SH) groups attached. DMSA has the ability to form stable complexes with heavy metals, making it a useful compound in the medical field for treating heavy metal poisoning.
Uses
Used in Medical Applications:
Dimercaptosuccinic acid is used as a chelating agent for the treatment of mercury and lead poisonings. It has a high affinity for these toxic heavy metals, effectively binding to them and facilitating their excretion from the body. This helps to reduce the toxic effects of mercury and lead on various organs, including the kidneys, brain, and nervous system.
In addition to its use in treating mercury and lead poisoning, DMSA has also been investigated for its potential in treating other heavy metal poisoning cases, such as arsenic and cadmium poisoning. However, its efficacy in these cases may vary, and further research is needed to establish its effectiveness.
Used in Environmental Applications:
Dimercaptosuccinic acid can also be used in environmental applications for the removal of heavy metals from contaminated water and soil. Its chelating properties allow it to bind to heavy metal ions, forming stable complexes that can be more easily removed from the environment. This can be particularly useful in the remediation of sites affected by industrial pollution or in the treatment of wastewater from various industries.
Used in Analytical Chemistry:
In analytical chemistry, DMSA can be employed as a reagent for the detection and quantification of heavy metal ions. Its ability to form stable complexes with these ions can be utilized in colorimetric or spectrophotometric assays, providing a sensitive and selective method for the analysis of heavy metal concentrations in various samples.
Check Digit Verification of cas no
The CAS Registry Mumber 2418-14-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,1 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2418-14:
(6*2)+(5*4)+(4*1)+(3*8)+(2*1)+(1*4)=66
66 % 10 = 6
So 2418-14-6 is a valid CAS Registry Number.
