Chemspider

Welcome to Norecopa, chemspider, Norway's 3R platform! Searches can be performed by chemical names Systematic names; Synonyms; Trade names and Database chemspider and chemical structure structures may be drawn on the website or structures may be imported from a personal computer.

ChemSpider is a freely accessible online database of chemicals owned by the Royal Society of Chemistry. The database sources include: [8]. The ChemSpider database can be updated with user contributions including chemical structure deposition, spectra deposition and user curation. This is a crowdsourcing approach to develop an online chemistry database. Crowdsourced based curation of the data has produced a dictionary of chemical names associated with chemical structures that has been used in text-mining applications of the biomedical and chemical literature.

For several months now we have been working hard to rebuild ChemSpider from the ground up. This is redeveloping the technical implementation of the site, as well as a complete reassessment of the website; how it looks, how it works and the data that we present. We hope this new ChemSpider site, while not a complete copy of the features in the old site, will provide access to all the information that you need in a more intuitive and user-friendly way. While we continue to refine the new site we have made a preview version of the new interface available as Beta. ChemSpider only contains the data for the first 5 million ChemSpider records for the moment. Once we are happy that the new site is ready it will replace the current ChemSpider site. This allows us to provide you with the ability to try improved design, provide feedback, and should you need to still switch back to the familiar interface. We are still adding functionality and tweaking the data, but your feedback will help us to validate where we have made improvements and where we still need to do more. Some record tabs which were based on out-of-date or limited availability data have been retired. Other features like structure searching are yet to be added to the new website as we look for a solution to replace the one currently used on ChemSpider. Please try it out and decide for yourself.

Link based search: Taxol. ChemSpider is a free access service providing a structure centric community for chemists. Providing access to millions of chemical structures and integration to a multitude of other online services, ChemSpider is the richest single source of structure-based chemistry information. ChemSpider is a chemistry search engine. It has been built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and make it available to everybody, at no charge.

Select the More Searches menu from the top toolbar and choose Structure Search from the dropdown menu. The Draw Structure tab may be selected default setting but this tab may not not be your current default setting. Example showing how you can use the Convert structure option to generate an editable structure from a name. Simple Structure Advanced History. Advanced Search Advanced searching is one of the best ways of finding information about a compound or helping to identify an unknown.

Cholesterol skeleton without stereochemistry. The webinar series will focus on how data is enabling research — the current challenges and examples and how a better future can be created using chemistry data. In order to manage these challenges, we are taking the time to refine our processes on new depositions, and periodically checking our progress by running subsets of the full ChemSpider database through our filters. Recently we have focused on bulk identification and removal of erroneous data. It is owned by the Royal Society of Chemistry. Database of chemicals owned by the Royal Society of Chemistry. Created as a free, three-part series for chemical scientists working with data, learn more about chemistry data today, what the future holds, and the current challenges and opportunities of digital chemistry data. Comments Off on Webinar 1: Where are we with digital chemistry data? We then compared the original text of the property as it was written in the original file to how that text was parsed and mapped by our deposition system. Comments Off on Webinar 2: What does the future hold? Please note that we cannot reply to you unless you send us an email. Elevate your data practices Created as a free, three-part series for chemical scientists working with data, learn more about chemistry data today, what the future holds, and the current challenges and opportunities of digital chemistry data. What are you looking for? The intention is to collect practical experience of how to conduct useful chemical synthesis in the lab. Watch the recording 18 Nov

ChemSpider is a powerful tool for finding chemical information: we have lots of different types of information and a rich selection of search tools.

RadioButtonList field Ja, jeg fant det Nei, jeg fant det ikke. More than million chemical structures, properties and associated information. Experimental Properties We retrieved all 6. Held on 17 October — recording available on-demand. Comments Off on Webinar 1: Where are we with digital chemistry data? Although structure D is unchanged, this representation has other problems: incorrect valence on Fe and no representation of the aromaticity of the cyclopentadienyl ligands.

We ran a series of regular expression string searches to identify synonyms with incorrect metadata, as well as malformed or otherwise erroneous synonyms.
