MarvinView is an advanced chemical viewer for single and multiple chemical structures, queries, reactions and non chemical data included in the file. MarvinView allows easy scrolling of thousands of molecules either in a grid view or in a spreadsheet view. In addition to the support of reporting and publishing MarvinView also enables users to perform structure calculations. Learn more about MarvinView »

Marvin Live

Product Type:application
Interfaces:GUI ( Web )API ( JavaScript )

Drug discovery processes increasingly involve remote research partners, such as CROs, consultants, or off-site colleagues. Circulating ideas within project teams becomes therefore more and more cumbersome with regular tools. Marvin Live is built for today’s project and design meetings. Learn more about Marvin Live »
