从China供应商批量进口(-)-2,3-O-Isopropylidene-D-Threitol

(-)-2,3-O-Isopropylidene-D-threitol is a protected chiral diol used as a building block in asymmetric synthesis. Shijiazhuang Chirals Chemical Co., Ltd supplies this compound from Shijiazhuang, China, with a CAS Registry Number of 73346-74-4 and EINECS number 277-391-1. The molecule has a formula of C7H14O4 and a molecular weight of 162.18 g/mol, with a reported melting point range of 42-48°C.

The isopropylidene protecting group on the 2,3-positions leaves the primary hydroxyl groups available for selective functionalisation, making this intermediate useful in pharmaceutical synthesis and chiral ligand preparation. It is typically handled as a white to off-white crystalline solid and should be stored under cool, dry conditions to maintain stability. Trade terms such as FOB and CIF are available, though specific MOQ, pricing, and lead times should be confirmed directly with the supplier.

Shijiazhuang Chirals Chemical Co., Ltd is based in Shijiazhuang High-Tech Industrial Development Zone, Shijiazhuang 050091, China. The company focuses on chiral intermediates and specialty building blocks used in pharmaceutical and fine chemical synthesis.
