Unterborsaeureaethylester, also known as ethyl borate, is a chemical compound with the formula C2H5OB(OH)2. It is formed by the reaction of boric acid (H3BO3) with ethanol (C2H5OH). Ethyl borate is a colorless, viscous liquid that is soluble in water and has a pungent odor. It is used as a flame retardant, particularly in the production of textiles, paper, and plastics, due to its ability to release water and boric acid when heated, which helps to slow down the combustion process. Additionally, it has applications in the manufacturing of glass, ceramics, and as a component in some types of adhesives. Ethyl borate is also known for its ability to act as a Lewis acid, which can be useful in various chemical reactions.
The CAS Registry Mumber 1630-81-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 0 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1630-81: (6*1)+(5*6)+(4*3)+(3*0)+(2*8)+(1*1)=65 65 % 10 = 5 So 1630-81-5 is a valid CAS Registry Number.
