Welcome!

Hello, and welcome to Wikipedia! Thank you for your contributions; however, please remember the essential rule of respecting copyrights. Edits to Wikipedia, such as your edit to the page Asoprisnil, may not contain material from copyrighted sources unless that text is available under a suitable free license. It is almost never okay to copy extensive text out of a book or website and paste it into a Wikipedia article with little or no alteration, though you can clearly and briefly quote copyrighted text in the right circumstances. Content that does not comply with this legal rule must be removed. For more information on this, see:

• Copying text from other sources
• Policy on copyright
• Frequently asked questions on Wikipedia's copyright policy
• Policy and guideline on non-free content

If you still have questions, there is the Teahouse, or you can and someone will be along to answer it shortly. As you get started, you may find the pages below to be helpful.

Wikipedia and copyright

Hello Yogi Yolk! Your additions to Etonogestrel have been removed in whole or in part, as they appear to have added copyrighted content without evidence that the source material is in the public domain or has been released by its owner or legal agent under a suitably free and compatible copyright license—to request such a release, see Wikipedia:Requesting copyright permission. While we appreciate your contributions to Wikipedia, it's important to understand and adhere to guidelines about using information from sources to prevent copyright and plagiarism issues. Here are the key points:

• Limited quotation: You may only copy or translate a small portion of a source. Any direct quotations must be enclosed in double quotation marks (") and properly cited using an inline citation. More information is available on the non-free content page. To learn how to cite a source, see Help:Referencing for beginners.
• Paraphrasing: Beyond limited quotations, you are required to put all information in your own words. Following the source's wording too closely can lead to copyright issues and is not permitted; see Wikipedia:Close paraphrasing. Even when paraphrasing, you must still cite your sources as appropriate.
• Image use guidelines: In most scenarios, only freely licensed or public domain images may be used and these should be uploaded to our sister project, Wikimedia Commons. In some scenarios, non-freely copyrighted content can be used if they meet all ten of our non-free content criteria; Wikipedia:Plain and simple non-free content guide may help with determining a file's eligibility.
• Copyrighted material donation: If you hold the copyright to the content you want to copy, or are a legally designated agent, you may be able to license the text for publication here. Please see Wikipedia:Donating copyrighted materials.
• Copying and translation within Wikipedia: Wikipedia articles can be copied or translated, however they must have proper attribution in accordance with Wikipedia:Copying within Wikipedia. For translation, see Help:Translation § Licensing.

It's very important that contributors understand and follow these practices. Persistent failure to comply may result in being blocked from editing. If you have any questions or need further clarification, please ask them here on this page, or leave a message on my talk page. Thank you. GoldRomean (talk) 03:10, 23 January 2026 (UTC)

Synthesis sections

If you're going to add synthesis sections to articles, please 1) follow WP:PHARMMOS and WP:MEDMOS article structure by always placing the "Synthesis" section under the "Chemistry" section; and 2) please include "class=skin-invert-image" on the synthesis image diagrams for dark mode. Otherwise others like me have to make these changes after you add them. And it's not always easy to follow where you've added things since you use different accounts. Thank you. – AlyInWikiWonderland (talk, contribs) 21:27, 27 January 2026 (UTC)

Also, do not use patents. They fail Wikipedia's "reliable sources" rule. Only secondary sources, like review articles and books should be used. That means unfortunately we often cannot have synthesis sections because no such sources exist. Like it or not, those are the rules. DMacks (talk) 12:33, 3 February 2026 (UTC)

Disambiguation link notification for February 3

Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Dienolone, a link pointing to the disambiguation page PVP was added. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)
