40692-21-5 Usage
Uses
Used in Pharmaceutical Industry:
2-ethyl-2-(3-methoxyphenyl)butyronitrile is used as an intermediate in the synthesis of Embutramide (E521010), a potent pharmaceutical sedative drug. Its role in the production process is essential, as it contributes to the drug's sedative properties and effectiveness in treating various conditions that require sedation.
Used in Analytical Studies:
In the field of analytical chemistry, 2-ethyl-2-(3-methoxyphenyl)butyronitrile is utilized for the detection of Embutramide in human blood samples. High-performance liquid chromatography (HPLC) with photodiode-array UV detection is employed to identify and quantify the presence of the sedative drug, providing valuable information for medical and forensic applications.
Check Digit Verification of cas no
The CAS Registry Mumber 40692-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,9 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40692-21:
(7*4)+(6*0)+(5*6)+(4*9)+(3*2)+(2*2)+(1*1)=105
105 % 10 = 5
So 40692-21-5 is a valid CAS Registry Number.
