MonomerChem Inc uses three bill rates A, B, and C, so that requisitions for synthesis of compounds where experimentals already exist in the literature are much less costly than a custom requisition where experimentals must be altered or designed. Thus an eight step synthesis where procedures are spelled out could be produced and delivered at less than half the cost of an eight step synthesis where most of the chemistry has yet to be demonstrated. This having been said, our bill rates for compound requisitions where some or all of the chemistry is unknown remain highly competitive. We invite you to compare rates by forwarding your compound requests to us.
