Dear ,Thank you for your email.I’m interested in 1,2-Dimethyl-4-methylene-cyclopenteneCAS number 83615-96-7I am aware how uncommon the product is.Can you please send me your Safety Data Sheets for this substance? We are still at a research level, assessing on its application and that is why I need the Safety Data Sheets (SDS or MSDS) before my procurement team deals with the purchase itself.Once I give them the green light on the product purchase they will contact you for the price quote.Thank you very much for your time.Best regards,
