The Problem with Traditional Chemistry Databases
For decades, chemists, students, and researchers have faced a frustrating limitation: every chemistry database requires you to know the exact molecular formula before you can find a compound.
Want to find compounds containing Carbon and Nitrogen? You need to know it's CN, C₂N₂, HCN, or one of thousands of other specific formulas. This creates a fundamental barrier to chemical discovery and learning.
The Traditional Approach
Tools like PubChem, ChemSpider, and other databases work like this: - Enter exact formula (H₂O, NaCl, C₆H₁₂O₆) - Enter compound name (if you know it) - Enter CAS number (if you have it)
But what if you don't know the formula?
What if you're a student exploring what compounds Carbon and Oxygen can form? What if you're a researcher wondering what molecules contain Iron, Carbon, and Nitrogen? There was no tool for that. Until now.
The CompoundLookup Solution
CompoundLookup is the world's first and only chemistry tool that lets you search compounds by simply selecting elements from the periodic table.
How It Works
- Select Elements - Click on any elements you're interested in (up to 5)
- View All Compounds - See every known compound containing those elements
- Explore & Learn - Browse formulas, names, and properties
It's that simple. No formulas to memorize. No compound names to know. Just pure element-based discovery.
Why This Matters
For Students - Explore chemistry intuitively - Understand how elements combine - Discover compounds you never knew existed
For Researchers - Quick preliminary research - Find potential compounds for study - Explore element combinations rapidly
For Educators - Demonstrate chemical bonding concepts - Create engaging learning experiences - Show real-world compound examples
The Technology Behind CompoundLookup
We've indexed millions of compounds from PubChem, organizing them by their constituent elements. Our unique database structure allows instant retrieval of compounds based on any element combination.
No other tool has attempted this because of the complexity involved: - Parsing millions of molecular formulas - Creating efficient element-based indexes - Building a user-friendly periodic table interface
We solved these challenges to bring you a tool that didn't exist anywhere on the internet.
