What to do next

Use the right route for status, SCIP, and source questions

Status

Current legal state, Candidate List signals, and source-backed rationale

Go here for the framework answer block, listed dates, reasons, and the imported basis for the current EU status.

Obligations

Who needs to act, what to check, and whether SCIP matters

Use this when the question is operational: SCIP, article communication, threshold review, portfolio screening, or substitute work.

Why monitored

Why this substance is monitored in the EU

Use this when you want the hazard or legal basis behind the current status, not just the status label itself.

Alternatives

Potential substitutes and nearby molecules

Use this to branch into lower-pressure neighbors, same-class analogs, and candidate-list peers.

Changes

What changed over time

Use this when you want the timeline, not just the current state.

Sources

Verify where the data came from

Use this when you need to audit provenance before trusting a claim.

Action prompts

Fast compliance and screening routes

Article duties

Check Candidate List threshold and SCIP relevance

Use this when the substance may sit in articles, components, or imported goods and you need to confirm communication and SCIP workflows.

Source check

Verify the legal source before repeating the claim

Every summary should point back to the underlying authority surface. Use the source route when the exact notice, registry entry, or legal text matters.
