307974-61-4 Usage

Uses

Used in Pharmaceutical Industry:
Azithromycin B is used as an impurity in the formulation of Azithromycin for its antibiotic properties. As a part of the Azithromycin formulation, it contributes to the overall effectiveness of the antibiotic in treating bacterial infections.
Additionally, since Azithromycin B is related to Erythromycin A, it may also have potential applications in research and development for new antibiotics or as a reference compound in the study of macrolide antibiotics. However, it is important to note that Azithromycin B is an impurity and not the primary active ingredient in the Azithromycin formulation.

Form

Off-White to Yellow Solid

Check Digit Verification of cas no

The CAS Registry Mumber 307974-61-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,9,7 and 4 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 307974-61:
(8*3)+(7*0)+(6*7)+(5*9)+(4*7)+(3*4)+(2*6)+(1*1)=164
164 % 10 = 4
So 307974-61-4 is a valid CAS Registry Number.
