Omacycline 7-desmethyl impurity is a defined related substance associated with omadacycline, a tetracycline-class antibiotic, and it differs from the parent structure by the absence of a methyl group at the 7 position. Analysts working on this drug need the individual impurity because related-substance profiles are assessed peak by peak, and an authenticated standard is what allows a peak to be assigned with confidence. Uses include HPLC and LC-MS method development and validation, system suitability and resolution assessment, peak identification and estimation of the impurity in drug substance and drug product, as well as stability-indicating studies. The material is a yellow solid with the formula C28H38N4O7 and a molecular weight of 542.62. It requires storage at -80 °C ± 5 °C and shipment on dry ice, and is offered in a broad range of pack sizes from 1 mg to 250 mg, including 5 mg, 10 mg, 25 mg, 50 mg, 100 mg, 150 mg and 200 mg. Requests for a quotation or technical data are welcome.
