When an exported CSV is enough and when to convert the SDF yourself: build one row per record with SMILES and a stable key, link PNG pictures, avoid CSV and Excel traps, and check the row count.

A linker is an atom or chain of atoms that joins two parts of a molecule. This short answer covers common linker types, how linkers differ in scaffolds and conjugates, and why they are partial structures.
A canonical SMILES is the single string a toolkit writes for a molecule. This short answer explains why one molecule has many SMILES, why toolkits differ, and what to do before comparing patent structures.
Molecular glue degrader structures are small, and neighbouring examples may differ by one atom or stereocentre. A difference ledger, a stereo-first review routine and a cross-filing comparison keep those differences visible.
A comparison routine for BTK inhibitor patents: what to record for covalent versus non-covalent series, how to diff a new filing against an earlier extraction by core and structure key, and what to check twice.
In a chemical patent the compound is often a drawing, not a name. This explainer covers why drawings carry the chemistry, what a word search misses, how Markush drawings add a layer, and what recognition makes possible.
How CRO business development staff can read the chemistry in a prospective client’s patent, note chemistry types and rough complexity, and bring a page-referenced structure list to a scoping call.
A vendor-neutral buyer’s checklist for OCSR tools: evidence, inputs, outputs, review workflow, data handling, limits and pricing, with a copyable 13-row scorecard and a worked example of reading one accuracy claim.
A practical routine for getting a long chemical PDF under 50 MB: choose the pages that hold structures, split at natural breaks, lower resolution only as far as drawings stay legible, and check before upload.
A scaffold is the shared ring-and-linker framework of a compound series. This short answer defines it, gives examples in prose, and explains how it differs from a core and a Markush structure.
