I am interested in purchasing 100g of Allyloxypolyethyleneglycol with a molecular weight of 2000, where one end is an allyl group and the other is a hydroxyl (-OH) group. I previously purchased 100g of this product from another company for $80 USD, but the quality was unsatisfactory. Therefore, I would like to inquire about purchasing it from your esteemed company. Could you please provide me with the total cost, including shipping to [Your Location/Country - add this detail for accurate quote], and an estimated delivery time? Thank you for your time and assistance. Sincerely,
