ChemSpider

ChemSpider is a free chemical structure database providing fast access to over 130 million structures, properties and associated information. By integrating and linking compounds from more than 270 data sources, ChemSpider enables researchers to discover the most comprehensive view of freely available chemical data from a single online search. It is owned by the Royal Society of Chemistry. ChemSpider builds on the collected sources by adding additional properties, related information and links back to original data sources. ChemSpider offers text and structure searching to find compounds of interest and provides unique services to improve this data by curation and annotation and to integrate it with users’ applications.

ChemSpider是一款免费化学结构数据库，提供对超过5800万个结构、性质及其相关信息的快速访问。通过整合和链接来自超过400个数据源中的化合物，ChemSpider使研究人员能够通过单一在线搜索发现全面的可自由获取化学数据的全景。该数据库由皇家化学学会拥有。ChemSpider在收集到的资源基础上，通过添加额外的性质、相关信息和回溯至原始数据源的超链接进行扩展。ChemSpider提供文本和结构搜索功能以寻找感兴趣的化合物，并通过编纂、注释以及与用户应用的集成等独特服务，提高数据的品质。
