Top 10 Companies in the 1,2-Butylene Oxide (BO) Market (2026): Market Leaders Powering Global Production

MARKET INSIGHTS

Global 1,2-Butylene Oxide (BO) market size was valued at USD 54.5 million in 2024 and is projected to grow from USD 60.1 million in 2025 to USD 107 million by 2034, exhibiting a CAGR of 10.4% during the forecast period.

1,2-Butylene Oxide (BO), CAS No 106-88-7, is an essential reactive intermediate in organic synthesis. It plays a pivotal role in manufacturing polyether polyols for detergents, plasticizers, nonionic emulsifiers, and stabilizers for chlorinated solvents. Its versatility derives from its ability to participate in polymerization and hydration reactions, making it valuable across multiple industrial applications.

The market expansion is underpinned by rising demand from chemicals, plastics, and surfactants sectors. Regulatory hurdles arise from BO’s classification as a Category 2B carcinogen by IARC. The Asia‑Pacific region holds a 42% share, driven largely by China’s industrial growth. BASF dominates with 79% market share, while 99.5% purity products account for 95% of total demand, primarily used as chemical intermediates (61% share).
