The pharmaceutical industry places immense importance on controlling impurities within drug substances and products. For widely used antibiotics like Azithromycin, understanding and managing related compounds, including intermediates and potential impurities, is crucial for safety and efficacy. One such related compound, often discussed in the context of Azithromycin synthesis and quality control, is 9-Deoxo-9a-aza-9a-homo Erythromycin A Desmethyl Azithromycin (CAS 76801-85-9).

While CAS 76801-85-9 is primarily recognized as a key intermediate in the synthesis of Azithromycin, it's important for manufacturers to be aware of its presence and control throughout the production process. Regulatory bodies like the FDA and EMA have strict guidelines regarding the identification, quantification, and control of impurities in pharmaceutical products. Therefore, a reliable manufacturer and supplier of this intermediate must also provide comprehensive data on its characterization and potential for carry-over into the final API.

Research literature and pharmacopeial standards (such as USP and EP) often detail various related substances of Azithromycin. 9-Deoxo-9a-aza-9a-homo Erythromycin A Desmethyl Azithromycin, also known by synonyms like Azaerythromycin A or Desmethyl Azithromycin, is structurally very similar to Azithromycin. Its proper synthesis and purification are vital to minimize its presence in the final drug product. Pharmaceutical companies often purchase this compound as a reference standard for analytical method development and validation to accurately detect and quantify it within their Azithromycin batches.
