Questions

  1. What does "predominantly trans" mean for product 262668? Is there any guidance available on the amount of trans compared to cis?

    1 answer

    1. In this case, the term "predominantly trans" is not specifically defined, but based on analysis of previous lots, it appears to be between 95% and 98% trans. While this cannot be guaranteed for future lots, historical data suggests this range. It could be a helpful estimation to consider.
