76674-93-6 Usage
Uses
Used in Pharmaceutical Synthesis:
2-Methoxyimino-3-oxobutyric acid tert-butyl ester is used as an intermediate in the synthesis of Cefotaxime Bromoacetyl Analogue (C242940), which is an impurity of Cefotaxime (C242950). Cefotaxime is a broad-spectrum third-generation cephalosporin antibiotic, effective against a wide range of bacterial infections. The use of this ester in the synthesis process helps to improve the purity and quality of the final antibiotic product.
In the pharmaceutical industry, 2-Methoxyimino-3-oxobutyric acid tert-butyl ester plays a crucial role as a building block for the development of new drugs and the improvement of existing ones. Its unique chemical properties make it a valuable component in the synthesis of various active pharmaceutical ingredients, contributing to the advancement of medical treatments and therapies.
Check Digit Verification of cas no
The CAS Registry Mumber 76674-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,6,7 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76674-93:
(7*7)+(6*6)+(5*6)+(4*7)+(3*4)+(2*9)+(1*3)=176
176 % 10 = 6
So 76674-93-6 is a valid CAS Registry Number.
