Why does 1,3-pentadiene follow Markovnikov's rule in HBr addition?
From a market view, this chemistry underpins how refiners valorize C5 fractions. Piperylene grades below 40% purity are cheaper but less selective in downstream reactions. Buyers should match purity to their process—higher purity (>65%) commands a premium but reduces waste and improves resin color and thermal stability, which is critical for adhesive and paint applications.
