CHEMREFERENCE

ChemReference is made possible thanks to these tremendously great (and graciously open source) libraries and tools... ChemReference aims to be a full featured chemistry reference - a one stop shop for all the data and tools students and chemists need for their day-to-day tasks. It's got a long way to go before it's perfect, but I hope you'll find it useful in the meantime... Interactive periodic table and chemistry reference with an incredibly fast work flow. Full featured with data, trends, display modes, and conversions.
