13235-36-4 Usage
Description
Ethylenediaminetetraacetic acid tetrasodium salt, also known as sodium edetate, is a synthetic chelating agent that can be produced by reacting a basic solution of ethylenediamine with formaldehyde and sodium or hydrogen cyanide, followed by hydrolysis to form the salt. It is a white crystal powder with a purity of 99% minimum and has various applications in different industries due to its chelating properties.
Uses
Used in Medicine:
Ethylenediaminetetraacetic acid tetrasodium salt is used as a chelating agent for removing heavy metals, such as lead or mercury, from the blood. It is also used to lower blood levels of calcium and to control heart rhythm disturbances caused by certain heart medications.
Used in Food Industry:
In the food industry, Ethylenediaminetetraacetic acid tetrasodium salt is used as an additive in flume water for washing fruits and vegetables, ensuring their cleanliness and safety for consumption.
Used in Industrial Applications:
Ethylenediaminetetraacetic acid tetrasodium salt is used in the formulations of various industrial products, including anti-adhesive agents, corrosion inhibitors, anti-scaling agents, lubricant additives, and surface active agents. It is also utilized in photo-chemicals, textile treatment products and dyes, biocides (e.g., disinfectants, pest control products), and polishes and waxes.
Used in Research and Development:
Ethylenediaminetetraacetic acid tetrasodium salt is used as a reactant/reagent for the green preparation of O-allylhydroxylamines via organocatalytic oxidation of tertiary allylic amines followed by a [2,3]-Meisenheimer rearrangement, contributing to the advancement of chemical research and development.

Check Digit Verification of cas no
The CAS Registry Mumber 13235-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,3 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13235-36:
(7*1)+(6*3)+(5*2)+(4*3)+(3*5)+(2*3)+(1*6)=74
74 % 10 = 4
So 13235-36-4 is a valid CAS Registry Number.
