batch search

Batch search is how the CompTox Dashboard handles multi-substance questions. Instead of typing one chemical name at a time, you submit a list and the Dashboard resolves it against an inventory of 1,376,722 searchable chemicals. EPA describes the platform's access options as 'batch search, downloadable chemical lists and free CTX API access', positioning the three as complements: batch search for interactive list work, curated chemical lists for ready-made sets (300+ of them), and the CTX API for programmatic pipelines. Batch search earns its place when the input is an inventory - a supplier's ingredient list, a monitoring target list - and each member needs hazard and product-use data attached.

Chemical identification is unforgiving: the same substance travels under CAS numbers, DSSTox identifiers, and dozens of synonyms. If a tool only accepts single exact queries, screening a 500-item inventory becomes 500 fragile lookups and silent misses that bias any downstream risk assessment. Batch search concentrates that matching into one pass, so unresolved entries surface together where they can be fixed. Buyers comparing chemical sources should weigh whether the platform can absorb a list, not just a name - and whether the resolved hits expose substance identifiers stable enough to join on later, which is what the DSSTox substance identifier provides.

1. Confirm inventory scale: CompTox reports 1,376,722 chemicals searchable, so a candidate source should state comparable coverage explicitly.

1. Confirm the batch path exists: the platform's own short_description lists 'batch search, downloadable chemical lists and free CTX API access'.

1. Check for ready-made sets: 300+ curated chemical lists ship alongside batch search, useful for benchmarking your own list against standard groupings.

1. Check the automation route: if you outgrow interactive batches, the free CTX API is the programmatic counterpart on the same data.
