If you’ve ever used emergency contraception or oral birth control, you may have encountered Levonorgestrel. This synthetic hormone has been a cornerstone in reproductive health, providing fast-acting, effective protection against unintended pregnancy. According to the World Health Organization, Levonorgestrel is on the List of Essential Medicines due to its clinical safety and efficacy. But beyond its therapeutic role, it’s also critical to ensure its purity, especially when developing generic formulations.

Levonorgestrel belongs to the class of synthetic progestins, structurally related to the naturally occurring hormone progesterone. It works primarily by preventing ovulation, thickening cervical mucus to block sperm, and altering the uterine lining to inhibit implantation. The effectiveness of any Levonorgestrel-based pharmaceutical product depends not just on the active ingredient, but also on strict control of its impurities—compounds that can arise during manufacturing or storage.

At Axios Research, we specialize in synthesizing high-quality reference standards for pharmaceutical R&D. Below are key Levonorgestrel-related impurities that we offer for research and development purposes. These standards support drug manufacturers in maintaining regulatory compliance and ensuring consistent product quality.

Here are some Levonorgestrel impurities with available reference materials:

• Levonorgestrel EP Impurity O (AR-L00982): A critical impurity monitored in finished dosage forms. https://www.axios-research.com/products/levonorgestrel-ep-impurity-o
• 6-Hydroxy Levonorgestrel (AR-L06083): A hydroxylated metabolite often studied during stability and metabolism testing. https://www.axios-research.com/products/6-hydroxy-levonorgestrel
• Levonorgestrel EP Impurity Q (AR-L01569): A synthetic byproduct formed during manufacturing. https://www.axios-research.com/products/levonorgestrel-ep-impurity-q
• Levonorgestrel EP Impurity A (AR-L01559): Listed in the European Pharmacopoeia; used for compliance in impurity profiling. https://www.axios-research.com/products/levonorgestrel-ep-impurity-a-2
• Levonorgestrel Impurity I (AR-L01551): An identified degradation product used to assess formulation stability. https://www.axios-research.com/products/levonorgestrel-impurity-i

Maintaining the purity of Levonorgestrel is vital not only for therapeutic efficacy but also for patient safety. Regulatory authorities like the FDA and EMA mandate strict impurity profiling and qualification thresholds. By using certified impurity standards in testing protocols, pharmaceutical companies can ensure quality consistency across batches and formulations.

At Axios, your research is our passion. We are committed to supporting the pharmaceutical industry with high-quality impurity reference standards, custom synthesis, and analytical services. We continuously expand our product catalog to meet your evolving needs in formulation and regulatory science.
