What are the main synthesis routes and market challenges for 3-hydroxybutyraldehyde?
One practical issue is that 3-hydroxybutyraldehyde is often not isolated as a pure commercial product—many producers convert it immediately to crotonaldehyde or hydrogenate it to 1,3-butanediol. This means spot market availability is limited, and pricing is usually negotiated on a contract basis with acetaldehyde producers. For buyers, securing supply requires long-term relationships with integrated acetaldehyde-to-C4 derivatives plants rather than relying on merchant traders.
