Rimegepant sulfate api?

Do you mean you want the API name and identifiers for rimegepant in its sulfate form (as a salt), or something else about the API?

Here are the basics to help you decide:

- API concept: API stands for Active Pharmaceutical Ingredient. For rimegepant there are two common forms:
- Rimegepant (the free base) — the API used in the marketed Nurtec ODT product.
- Rimegepant sulfate — a salt form that can be used as an API for bulk manufacturing or formulation, depending on the supplier.

- If you’re procuring, you’ll often see:
- "Rimegepant" (free base) or
- "Rimegepant sulfate" (the salt form)

- What I can provide if you want exact identifiers:
- CAS numbers, PubChem CID, InChIKey, molecular formula and weight for either the free base or the sulfate salt.
- Synonyms and typical purity specifications used in API lots.
- Suggested data to request from suppliers (e.g., purity > 98%, residual solvents, moisture, HPLC assay).

If you’d like, tell me which exact identifiers you need (CAS, PubChem CID, InChIKey, etc.) and whether you want the free base or the sulfate salt. I can look up or summarize the precise details for you.
