Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Molecular Formula Determination, so you can see the experience inside your AI.

It does not authenticate your account with Molecular Formula Determination. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions Molecular Formula Determination owners ask.

  • 01

    How do I calculate the molecular formula?

    You can use the calculate_molecular_formula capability by providing the empirical formula and the target molar mass.

  • 02

    Can I use mass spectrometry data?

    Yes, the calculate_molecular_formula capability accepts an optional msMassData parameter to refine the molar mass using the molecular ion peak.

  • 03

    What is the degree of unsaturation?

    The degree of unsaturation represents the total number of rings and pi bonds in a molecule, which can be found using calculate_unsaturation.
