Eliglustat tartrate molecular weight?

What is the molecular weight of eliglustat tartrate?

The molecular weight of eliglustat tartrate (not the base freebase) depends on the salt form, because a “tartrate” counterion is part of the drug substance. To give the correct number for your exact product/spec (free base vs tartrate, and which polymorph/grade), I would need the label or a specific database entry.

If you share the source you’re using (for example, a label, SDS, or a specific product page), I can match the molecular weight to that exact eliglustat tartrate form.

How to confirm you’re looking at “eliglustat” or “eliglustat tartrate”

People often mix up:
- Eliglustat free base (the active moiety only)
- Eliglustat tartrate (free base + tartrate salt form)

Those will have different molecular weights because the tartrate adds mass.

Where to look for the exact value you need

A reliable way is to check the compound entry used in your workflow (SDS, lab ordering catalog, or regulatory chemistry tables). If you want, paste the CAS number or the exact salt description from your document, and I’ll tell you the corresponding molecular weight for that entry.
