β-p-Nitrophenyl-acrylsaeure, also known as β-p-Nitrophenylacrylic acid, is a chemical compound with the molecular formula C11H9NO4. It is a yellow crystalline solid that is soluble in organic solvents such as ethanol and acetone. β-p-Nitrophenyl-acrylsaeure is often used as a substrate in enzymatic assays, particularly for the detection and quantification of esterase and lipase enzymes. The β-p-Nitrophenylacrylic acid is hydrolyzed by these enzymes, releasing the yellow β-p-Nitrophenol, which can be easily quantified by measuring its absorbance at 405 nm. This makes it a valuable tool in biochemical research and diagnostic applications.

37992-32-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37992-32-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,9,9 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 37992-32:
(7*3)+(6*7)+(5*9)+(4*9)+(3*2)+(2*3)+(1*2)=158
158 % 10 = 8
So 37992-32-8 is a valid CAS Registry Number.
