"ChemSpider is a free-to-access collection of compound data from across the web. It aggregates chemical structures and their associated information into a single searchable repository and makes it available to everybody. ChemSpider builds on the collected sources by adding additional properties, related information and links back to original data sources."
PubChem is world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
This contains many thousands of pages of text, stories, pictures, and data that you get to by clicking on the individual elements on the front page. A commercial website that includes detailed technical data about the elements.
"Organic Chemistry Resources Worldwide is an intuitive reference guide for synthetic organic chemists. The site is structured around the daily tasks an organic chemist has to perform. The site is top-referred in search engines for searches on different topics concerning organic chemistry, such as organic chemistry conferences, jobs for organic chemists, organic chemistry patents, organic chemistry exhibitions .."
HSDB is a comprehensive, peer-reviewed toxicology data for about 5,000 chemicals. . It is enhanced with information on human exposure, industrial hygiene, emergency handling procedures, environmental fate and regulatory requirements.
Created by Princeton University, this guide will walk you through the basics for safely handling laboratory chemicals and equipment. The Introduction section has several references to Princeton-use the links on the left for more general information.
A free program for Microsoft Windows that can calculate the molecular weight and percent composition of chemical formulas and amino acids, providing a graphical user interface to edit the formulas and parsing options. It recognizes user-definable abbreviations, custom elemental isotopes, and can display up to 20 compounds simultaneously. It also includes a Mole/Mass Converter, Formula Finder, Capillary Flow Modeler, Amino Acid Notation Converter, Peptide Sequence Fragmentation Modeler, and built-in calculator.
NSF's goal is to support the people, ideas and tools that together make discovery possible. That's why we say NSF is "where discoveries begin." Learn about many of the advances made possible with NSF support in "Discoveries." If you're looking for a specific discovery, please use the Discovery search page.
Brought to you by the Physics in Society team at the Insitute of Physics. Let them be your guide and show you the best physics places on the web. All the sites in this database have been checked for accuracy and sorted into suitability for different age groups and levels of knowledge.
This is a comprehensive physics and astronomy online education, research and reference web site. In addition to providing high-quality content, PhysLink.com is a meeting place for professionals, students and other curious minds.
ChemCollective tutorials walk students through solving chemistry problems movies, text, and interactive tutors. Because the hints given by these tutors ultimately provide the solution to the problem, they are similar to worked examples in a textbook.
