Advanced Chemistry Development is pleased to announce another milestone - 130,000 downloads of ACD/ChemSketch! The lucky 130,000th downloader of ACD/ChemSketch freeware is Mr. David Singer, who is a student at the University of Leipzig, in Leipzig, Germany.

We are celebrating the occasion by awarding a free copy of ACD/ChemFolder 5.0. ACD/ChemFolder is described in more detail here and has several new features added in the recent release.

If you would like to "test drive" the download prize software, a one-month evaluation copy is available at our download page. And many, many sample databases are available for ChemFolder; download them for free here.

With its intuitive chemical drawing interface and its powerful data organization, archiving, and search capabilities, ACD/ChemFolder will help you keep track of molecules, references, properties and links that are important to your thesis and laboratory work. Congratulations on your prize, Mr. Singer, and good luck in your studies!

Coupled with our responsiveness to users' requests made via our ACD/Labs Freeware Forum and our provision of the FREE BASIC programming language, CHEMBASIC, users have informed us that ChemSketch is certainly the most intuitive, flexible and fastest developing structure drawing software available today... and it's free! With an increasing number of available GOODIES to add into the package and world renowned reviewers talking about us we are ecstatic with the response we have received from the public. When you consider that the package is ALSO integrated with the SpecViewer and can generate the following properties using our algorithms: molar refractivity, molar volume, parachor, index of refraction, surface tension, density, dielectric constant and polarizability, again for FREE, it's no wonder that our web site now averages over 200 downloads per night!!! We thank you for your feedback and suggestions... it's what helps to make Advanced Chemistry Development software world class! Download your copy now.
