Uses and Applications


Rifamycin O is not a frontline antibiotic but plays a pivotal role in the pharmaceutical industry, particularly in the production and quality assurance of rifamycin derivatives. Its primary applications include:

  • Rifaximin Intermediate and Reference Standard: Rifamycin O is identified as Rifaximin EP Impurity F, a critical reference standard used in the quality control of Rifaximin (ChemicalBook). Rifaximin, a rifamycin derivative, is approved for treating travelers’ diarrhea and hepatic encephalopathy. By serving as an impurity standard, Rifamycin O helps ensure the purity and safety of Rifaximin during manufacturing.
  • Pharmaceutical Research: As a member of the rifamycin family, Rifamycin O shares structural similarities with other rifamycins, which inhibit bacterial DNA-dependent RNA polymerase (Rifamycin). This makes it valuable in research settings for studying the mechanisms of rifamycin antibiotics or developing new derivatives.
  • Potential Intermediate in Synthesis: Rifamycin O is likely used as an intermediate in the synthesis of other rifamycin-based compounds, given its chemical structure and relation to the rifamycin family. Its role in the production process underscores its importance in the pharmaceutical supply chain.

These applications highlight Rifamycin O’s significance in ensuring the quality and efficacy of rifamycin-based therapeutics, even though it is not used directly in clinical treatments.

Safety Information

Rifamycin O is classified as a hazardous substance, requiring careful handling to mitigate risks to human health and the environment. The following safety information is derived from ChemicalBook:
