Description
Anhydrochlortetracycline hydrochloride, also known as anhydrous chlortetracycline hydrochloride, is a degradation product of chlortetracycline. It is formed through an acid-catalyzed isomerization of the dimethylamino group at the C4 position. ANHYDROCHLORTETRACYCLINE HYDROCHLORIDE exhibits minimal antibiotic activity, and its presence is often indicative of improper storage and handling of chlortetracycline.
Uses
Used in Pharmaceutical Industry:
Anhydrochlortetracycline hydrochloride is used as a quality control indicator for the proper storage and handling of chlortetracycline. Its presence in a sample suggests that the chlortetracycline has been exposed to unfavorable conditions, which may compromise its efficacy as an antibiotic.
Used in Research and Development:
In the field of pharmaceutical research and development, anhydrochlortetracycline hydrochloride can be utilized as a reference compound to study the stability and degradation pathways of chlortetracycline and other related antibiotics. This information can be valuable in the development of improved storage and handling protocols, as well as in the design of more stable and effective drug formulations.
Used in Analytical Chemistry:
Anhydrochlortetracycline hydrochloride can be employed as a reference material in analytical chemistry for the development and validation of methods to detect and quantify degradation products in antibiotic samples. This can help ensure the quality and safety of pharmaceutical products by identifying and quantifying potential impurities and degradation products.
Check Digit Verification of cas no
The CAS Registry Mumber 4497-08-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4497-08:
(6*4)+(5*4)+(4*9)+(3*7)+(2*0)+(1*8)=109
109 % 10 = 9
So 4497-08-9 is a valid CAS Registry Number.
