🧪 Chemical Name Calculator
Look up common or trivial names for frequently encountered chemical formulas.
Enter the formula using standard chemical notation. Parentheses are supported for polyatomic groups (e.g., Al2(SO4)3).
How to Use This Calculator
Enter the chemical formula
Type the molecular or empirical formula exactly as written in lab notes or textbooks. Ensure correct capitalisation of element symbols.
Submit the query
Click “Find Chemical Name” to search the built-in reference table of common inorganic and organic compounds.
Review the result
If the compound is in the database, its preferred common name is displayed along with quick suggestions when multiple matches exist.
Use suggestions or expand
When no direct match is found, suggested similar formulas appear to help correct typos. For complex naming, consult IUPAC naming rules referenced below.
Formula
This tool matches input formulas to a curated list of frequently used chemical names and provides quick suggestions for near matches.
While the calculator does not generate systematic IUPAC names algorithmically, it covers the most common laboratory compounds, acids, bases, salts, and simple organics. For complex organic structures, combine this tool with a dedicated IUPAC nomenclature reference or cheminformatics software.
Example lookups
- H2SO4 → Sulfuric acid
- NaCl → Sodium chloride
- Ca(OH)2 → Calcium hydroxide
- CuSO4 → Copper(II) sulfate
Full Description
Remembering every chemical name for a formula can be tedious, especially when juggling classroom assignments, laboratory preparations, and safety documentation. This calculator provides an instant lookup for dozens of ubiquitous compounds, giving students and professionals a quick answer when a name momentarily escapes memory. It complements textbooks and periodic tables by focusing on the formulas you encounter most often in general chemistry, analytical labs, and introductory organic chemistry.
The curated list emphasises clear, common names while referencing oxidation states for transition metals to reinforce proper nomenclature. Suggestions for similar formulas help catch typographical errors and guide users toward the correct compound. For more advanced work, the tool encourages users to consult IUPAC naming guides, reinforcing good habits that bridge informal and formal nomenclature systems.

Frequently Asked Questions
Does this tool generate IUPAC names?
No. It provides common and conventional names for a curated set of compounds. For systematic nomenclature, consult IUPAC naming resources or cheminformatics software.
Why can't the calculator find my formula?
Only frequently encountered compounds are included. Check for typos, ensure correct capitalisation, and review the suggestions list. Complex organics and specialty reagents may not be covered.
Can I request additional compounds?
Yes. Add commonly needed formulas to the reference list in the source code or contact the maintainer with suggestions for future updates.
How accurate are oxidation state names?
Transition metal compounds include oxidation states based on standard inorganic nomenclature (e.g., iron(III) oxide). Always double-check for context-specific naming conventions.
Does the tool support hydrated salts?
Hydrates can be entered by appending the water molecules, such as CuSO4(H2O)5. If not found, the base salt name is shown and you can append “pentahydrate” manually.
