System to describe the chemical formulas for WEB

Brief description of the site and the CharChem system.

If you post on the Internet materials for chemistry, you probably wondered: how to insert a chemical formula in html?
easyChem system designed to solve this problem.
With the help of easyChem the formula described by special text commands, as close to the original form of the formulas. And then these descriptions are automatically displayed in the usual form for chemists.
For example, to derive the formula H2SO4 in the form of HTML is required this description: H<sub>2</sub>SO<sub>4</sub>. But the textual easyChem description looks much easier: H2SO4.

In that case you need to use the structural formulas, we have to add to your bitmap images. It is much more difficult than typing. And if you need a small correction, it can be a nightmare.
Using easyChem you can describe the structural formulas in the form of text commands. Although it is not as easy as H2SO4, but, in any case, they are easier to manage than bitmaps.

On this site you can read the description of formulas with easyChem, download the various system components or you can use a test stand for service information.

Key features of easyChem

  • Output linear formulas and reaction equations in the form of HTML.
  • The ability to build BB-codes for forums, calculate the molecular weight and get empirical formula.
  • Conclusion structural formulas in graphical form (can not support legacy browsers).
  • Conclusion of the Periodic table with the ability to specify the appearance and even interactive features.
