I'm reaching out to inquire about the pricing for both liter and gallon quantities of 1,4 butanediol. We are conducting a study to analyze the effects of microdosing 1,4 and 1,3 butanediol simultaneously, focusing on their combined benefits. We're interested in obtaining small quantities of lab-quality 1,4 butanediol for our research. Could you provide detailed pricing information and any additional requirements or specifications needed for our order? Your assistance would be greatly appreciated!
