Import Durene — Buy in Bulk from Supplier in China

Durene, or 1,2,4,5-tetramethylbenzene, is a crystalline aromatic hydrocarbon with the CAS number 95-93-2. This listing confirms its use as a precursor in organic synthesis, particularly for producing dianhydrides and triphenyltetraformic acid. The material is supplied in solid form with a purity level consistent with industrial-grade chemical intermediates, though exact assay data is not specified in the source.

Durene is typically produced via alkylation of xylene or through catalytic reforming processes. It is commonly used as a solvent and catalyst in pharmaceutical synthesis to enhance reaction efficiency and reduce by-products. In the chemical industry, it serves as a building block for dyes, coatings, and plasticizers. The compound is stable under standard storage conditions but requires dry, inert environments to prevent oxidation.

Buyers in the fine chemicals and pharmaceutical sectors source this material for intermediate synthesis. Packaging is typically in 25kg polyethylene-lined drums or bulk containers, though exact packaging details are not confirmed. Trade terms such as MOQ, Incoterms, and lead time are not stated and must be confirmed directly with the supplier. Shandong Saier Chemical Technology Development Co., Ltd. operates from Zibo, Shandong, a known hub for specialty chemical manufacturing.
