The synthesis of active pharmaceutical ingredients (APIs) often relies on a series of precisely manufactured chemical intermediates. For the widely used emergency contraceptive and hormonal therapy drug, Levonorgestrel, one such crucial building block is Ethylgonendione, identified by its CAS number 21800-83-9. This compound, also known as 18-Methylestr-4-en-3,17-dione, is central to creating the complex steroidal structure of Levonorgestrel.

As a leading Levonorgestrel intermediate manufacturer, understanding the exact specifications and reliable sourcing of Ethylgonendione is our priority. Its molecular formula, C19H26O2, and molecular weight of 286.41 are just the starting points for its application. The light yellow crystalline solid form and specific melting point are critical parameters that ensure its suitability for further chemical transformations.

For pharmaceutical companies and research institutions, the ability to buy Ethylgonendione from a trusted supplier in China offers significant advantages. These include competitive pricing, consistent quality, and often, greater flexibility in order volumes. When you purchase Ethylgonendione, you are investing in the foundational material for a vital medication.

The importance of sourcing this intermediate from a reputable manufacturer cannot be overstated. Impurities in the starting materials can propagate through the synthesis process, potentially affecting the final API's safety, efficacy, and regulatory compliance. Therefore, diligent quality control and a commitment to high purity standards are essential when procuring compounds like Levonorgestrel EP Impurity L, which shares the same CAS number and is closely related.

Researchers and procurement specialists seeking this compound often look for terms such as '13-Ethylgon-4-ene-3,17-dione price' or 'Norgestrel Related Compound L vendor' when initiating their search. By providing transparent information on product specifications and supply chain reliability, we aim to be the preferred partner for those needing this critical pharmaceutical intermediate. Contacting a dedicated Ethylgonendione supplier is the first step towards ensuring your production runs smoothly.

In summary, Ethylgonendione (CAS 21800-83-9) is an indispensable intermediate in the pharmaceutical industry, particularly for Levonorgestrel synthesis. Its availability from reliable manufacturers and suppliers, coupled with a focus on quality and competitive pricing, underpins the successful production of essential hormonal medications.
