Unlocking 5-Carbon Chemistry

Why Does 5-Carbon Matter?
Molecules consisting of even and odd number of carbons behave differently, significantly impacting the properties of products used in everyday life.
Today, companies around the world are paying a substantial premium for access to 5-carbon molecules, as they are difficult to extract from petroleum.
Pyran has been able to develop the world’s only clean technology that can intentionally produce 5-carbon products.
Pyran’s 1,5 PDO Delivers a Triple Win
Until now, diol customers have been forced to choose between limited, high cost 1,5 PDO supplies or using a 6-carbon diol. Pyran’s initial product 1,5 PDO (pentanediol) is changing that paradigm, enabling:
PERFORMANCE
1,5 PDO polyols that perform better on heat, water, oil, and weather resistance.
Pyran’s proprietary process yields 1,5 PDO at prices equivalent to or below those of
1,6 HDO.
LOW COST
RENEWABLE
Pyran converts renewable agricultural products into 1,5 PDO with no harmful byproducts.
100% Biobased 1,5 PDO
Pyran’s 1,5 PDO has been certified as 100% biobased by the USDA BioPreferred® Program.
