MARKET INSIGHTS

Global (S)-1,2-Butylene oxide market size was valued at USD 78.4 million in 2025. The market is projected to grow from USD 83.1 million in 2026 to USD 138.6 million by 2034, exhibiting a CAGR of 6.6% during the forecast period.

(S)-1,2-Butylene oxide, also known as (S)-1,2-epoxybutane, is a chiral epoxide compound with the molecular formula C₄H₈O. It is the optically active (S)-enantiomer of 1,2-butylene oxide, characterized by a three‑membered cyclic ether ring that imparts high chemical reactivity. This compound serves as a critical chiral building block and intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals, where stereochemical precision is essential to the performance and safety of the end product.

The market is gaining steady momentum, driven primarily by the expanding demand for enantiopure intermediates in pharmaceutical synthesis, where regulatory agencies increasingly require stereospecific active pharmaceutical ingredients (APIs). Furthermore, growing applications in the production of chiral ligands, surfactants, and polymer modifiers are broadening its industrial relevance. Key producers operating in this space include TCI Chemicals, Sigma‑Aldrich (Merck KGaA), and Thermo Fisher Scientific, among other specialty chemical manufacturers with dedicated chiral chemistry portfolios.
