Bis-(4-ethoxycarbonyl-phenyl)-carbodiimide, also known as EDC, is a widely used chemical cross-linking agent in various fields, including biochemistry, molecular biology, and materials science. It is an organic compound with the chemical formula C16H18N2O6, characterized by its ability to activate carboxyl groups for coupling reactions. EDC is particularly effective in promoting the formation of amide bonds between carboxylic acids and amines, which is crucial for the synthesis of peptides, proteins, and other biomolecules. Its reactivity arises from its ability to form an intermediate active ester, which then reacts with a nucleophile, such as an amine, to form a stable amide bond. EDC is also known for its mild reaction conditions and high specificity, making it a preferred choice in many laboratory applications.
The CAS Registry Mumber 745-92-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,4 and 5 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 745-92: (5*7)+(4*4)+(3*5)+(2*9)+(1*2)=86 86 % 10 = 6 So 745-92-6 is a valid CAS Registry Number.
