Everything a chemical catalog needs to be searchable. Completely free, forever.
Structure Search
Shoppers draw a molecule and get matching products:
- Exact match on the canonical SMILES
- Substructure with fingerprint screening
- Stereo and isotope aware
- Matched by RDKit in the browser
Typed Search
One box for SMILES, InChI, CAS numbers, catalog numbers and product names. Structure-shaped text lands in the editor; everything else is looked up on the server.
Chemistry Fields
Every product gets a Chemistry tab:
- SMILES, CAS, formula and weight
- Structure drawing on the product page
- CSV import with supplier column names
- Index builder with a drawing per card
Your Theme's Cards
Results render through WooCommerce's own product loop:
- Grid or list, 1 to 6 columns
- Wide or full width
- Start open or behind a button
- Colours from your theme palette
Search Activity
30-day summary on the admin screen: searches by structure and by name, the share that found nothing, and the top missing items buyers asked for.
Block & Shortcode
A Structure Search block and a [chemical_structure_search] shortcode with heading, button text, accent, width, columns and layout attributes.
Similarity Search
A checkbox that also returns the products closest to what was drawn, each scored, so a buyer who cannot find the exact compound is shown the nearest thing you stock.
03 .
For catalogs that need more than search: enrichment, bulk import and demand insight.
CAS to Structure Enrichment
Products with a CAS number but no structure are resolved through PubChem in the background, with a review queue before anything is written to the product.
SDF Import
Import vendor SDF files with field mapping and a preview, creating or updating products with structures, identifiers and prices in one pass.
Search Demand Report
Every query by kind, with a daily trend, filters, retention control and CSV export. See what buyers draw that you don't sell.
Salt, Stereo & Tautomer Modes
Match the parent compound regardless of salt form, choose strict or relaxed stereo, and treat tautomers as one structure. On the Pro roadmap.
Batch List Search
Paste a list of CAS numbers or SMILES and get a hit table with prices and links, ready to add to the cart. On the Pro roadmap.
Licence, Updates & Support
Automatic updates from branchingsoftware.com, a 7-day grace period if the licence server is unreachable, and email support from the people who wrote the plugin. The free plugin stays untouched on wordpress.org.

Does the search send my catalog anywhere?
No. The index is a small file built in your admin and served from your own uploads folder, and every search runs in the shopper's browser with RDKit. There is no external service and no per-search fee.
Do I have to enter a SMILES for every product?
No. Type one on the product, import a CSV using your supplier's column names, or let Pro resolve CAS numbers to structures through PubChem and import vendor SDF files.
Will it look like the rest of my shop?
Yes. Results render through WooCommerce's own product loop, so cards match your theme. Colours, corner radius, width and columns are set in the Appearance tab or on the block.
How fast is the first search?
The editor and the search engine load only when the drawer opens, pre-warmed as soon as the shopper reaches for the button, with precompressed assets. Warm searches return in well under a second.
What does Pro add?
Similarity search, CAS-to-structure enrichment, SDF import, the full search demand report with CSV export and email support, as a separate add-on that leaves the free plugin untouched.
How much does Chemical Structure Search Pro cost?
Pro lists at $199 per year for one site ($349 for three sites, $799 for 25). Waitlist subscribers lock founders pricing from $119 per year and keep that price for as long as they stay subscribed.
