194491-31-1 Usage
Chemical Properties
white to slightly yellow crystalline powder
Uses
Different sources of media describe the Uses of 194491-31-1 differently. You can refer to the following data:
1. Ethylenediaminetetraacetic acid tetrasodium salt hydrate is used as an inhibitor of metal ligand proteases. It also acts as a chelator of zinc ion in the active site of metalloproteases. It is used as an anticoagulant and also used in the fluorometric determination of beryllium.
2. Ethylenediaminetetraacetic acid tetrasodium salt hydrate has been used as an antimicrobial agent during biological ink preparation for use in biopolytronics.
3. EDTA is an inhibitor of metalloproteases, at effective concentrations of 1-10 mM. EDTA acts as a chelator of the zinc ion in the active site of metalloproteases, and can also inhibit other metal ion-dependent proteases such as calcium-dependent cysteine proteases. For use as an anticoagulant, disodium or tripotassium salts of EDTA are most commonly used. The optimal concentration is 1.5 mg per ml of blood.
General Description
Ethylenediaminetetraacetic acid is a poylaminocarboxylic acid commonly used as a complexing agent.
Check Digit Verification of cas no
The CAS Registry Mumber 194491-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,9 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 194491-31:
(8*1)+(7*9)+(6*4)+(5*4)+(4*9)+(3*1)+(2*3)+(1*1)=161
161 % 10 = 1
So 194491-31-1 is a valid CAS Registry Number.
