Questions about Allyl isothiocyanate testing

Is the $250 test the same as USP monograph testing?

No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Allyl Isothiocyanate monograph is available and quoted.

Why is allyl isothiocyanate not tested by standard HPLC?

It is a small, volatile liquid with weak UV absorbance, so the lab uses a detection method suited to the compound. The test also shows other volatile sulfur compounds and solvents in the same run.

Does allyl isothiocyanate degrade?

Yes. It reacts slowly with water and breaks down with heat and light, so older or poorly sealed samples can read low. Keep samples tightly closed and cool before shipping.

Can natural and synthetic mustard oil be told apart?

The main compound is the same either way. The minor volatiles in the profile can point to a natural or synthetic source, but that is an observation, not a confirmation of origin.
