The three-dimensional structures of organic compounds can be represented by different projections. Common Projections of organic compounds include Fischer projection, Sawhorse projection, and Newman projection.

The OSIRIS Property Explorer lets you draw chemical structures and calculates on-the-fly various drug-relevant properties whenever a structure is valid. Prediction results are valued and color coded. Properties with high risks of undesired effects like mutagenicity or a poor intestinal absorption are shown in red .

In our study of organic chemistry, it will become extremely important to be able to quickly recognize the most common functional groups, because they are the key structural elements that define how organic molecules react.

At last count (2014), over 326,000 compounds have been isolated and characterized from organisms. We refer to these molecules as “natural products”. Among these 326,000 natural products are many familiar names – chlorophyll, caffeine, vitamin C, riboflavin, and erythromycin, to name just a few.

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.
