What free chemistry tools are available in MolDraw?

MolDraw includes free chemistry tools for SMILES, InChI, InChIKey, MOL, SDF, PDB, PDBQT, MOL2, CID lookup, IUPAC conversion, molarity, molality, dilution, solution preparation, equation balancing, TLC diagrams, and periodic table lookup.

Are MolDraw chemistry tools connected to the molecule editor?

MolDraw tools complement the main editor. You can draw molecules in the editor, copy identifiers, use converters and calculators, then return to the editor or related guides.

Free Chemistry Tools and Calculators

MolDraw includes a growing tools hub for chemistry students, educators, researchers, and lab teams. This guide links the most useful converters, calculators, structure utilities, and teaching tools in one SEO-friendly reference page.

Overview

Use the MolDraw Tools Hub when you need quick chemistry utilities without leaving the browser. The tools are grouped around common workflows: converting identifiers, preparing solutions, drawing structures, balancing equations, making TLC diagrams, and checking periodic table data.

Short answer: MolDraw tools cover chemistry converters, concentration calculators, structure utilities, periodic table lookup, TLC diagrams, and file-format helpers for everyday chemistry work.

Chemistry Converters

Converter pages help move between common chemical identifiers and file formats. They are useful when a database, notebook, docking workflow, or drawing tool expects a specific format.

SMILES and structure converters

Convert between SMILES, 2D structures, MOL, SDF, MOL2, PDB, and PDBQT formats.

SMILES to structure SMILES to 3D SMILES to MOL SMILES to SDF SMILES to PDB SMILES to PDBQT

Identifier converters

Resolve and convert InChI, InChIKey, IUPAC, CID, and SMILES identifiers.

SMILES to InChI SMILES to InChIKey InChI to SMILES InChIKey to SMILES IUPAC to SMILES SMILES to IUPAC CID to SMILES

Chemistry Calculators

Calculator tools support routine classroom and wet-lab calculations such as molarity, molality, dilution, and solution preparation.

FAQ

What is the best starting point?

Start with the Tools Hub for browsing, or open the MolDraw editor if you already have a molecule to draw or paste.

Are these tools free?

Yes. MolDraw’s core browser-based tools and calculators are free to use.

Which tool should I use for a molecule identifier?

Use SMILES, InChI, InChIKey, IUPAC, and CID converter pages depending on the identifier you have and the format you need.
