How to Use Molecular Descriptors
Commercially Available Online Web Server
Calculate common 2D molecular descriptors from SMILES, SDF, or CCD inputs.
Molecular Descriptors calculates a compact panel of physicochemical properties for small molecules. Submit up to 500 molecules in SMILES, SDF, or Chemical Component Dictionary format and receive a CSV with one row per input. The panel includes molecular weight, calculated lipophilicity (cLogP), topological polar surface area (TPSA), hydrogen-bond donors and acceptors, rotatable bonds, ring counts, and other structural properties.
How Molecular Descriptors Works
The Neurosnap SDK uses RDKit to parse each molecule and calculate descriptors from its molecular graph. The output also includes canonical SMILES, molecular formula, heavy-atom and heteroatom counts, fraction of sp3 carbons, formal charge, and quantitative estimate of drug-likeness (QED). These are calculated descriptors rather than measured properties or activity predictions. Because the panel is based on molecular connectivity, 3D coordinates are not needed. Use consistent structures, protonation states, and tautomer conventions when comparing compounds.
What is Neurosnap?
Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.
Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.
