Explore our certified range of high-grade industrial intermediates, solvents, and specialty compounds manufactured at our modern facility.
1,2,4,5-Tetramethylbenzene, commonly referred to as Durene (CAS No. 95-93-2), represents a fundamental chemical building block in modern specialty polymer fabrication and organic synthesis. With its highly symmetric alkyl aromatic structure, it is the primary precursor for the synthesis of Pyromellitic Dianhydride (PMDA), which in turn acts as the cornerstone monomer for high-performance polyimide (PI) films, aerospace coatings, and high-temperature-resistant engineered plastics.
On a global scale, the demand for high-purity 1,2,4,5-Tetramethylbenzene continues to escalate, driven by the expansion of the electronics manufacturing sector, structural aerospace engineering projects, and specialty curing agents. Modern industrial consumers look for dependable, large-capacity manufacturers capable of delivering batch-to-batch consistency with purity thresholds exceeding 98.5% and up to 99.5%.
Shandong Saier Chemical stands at the forefront of this industry. Strategically located within the Qilu Chemical Industrial Park, our production facility leverages high-temperature cracking feedstock streams and state-of-the-art fractional distillation systems to supply global markets.

Founded in December 2004 with a substantial registered capital of 60 million yuan, Shandong Saier Chemical Technology Development Co., Ltd. has developed into a premium developer of specialty solvents and fine chemicals. Located in Zibo City, Shandong Province, our infrastructure sits at the heart of the national Qilu Chemical Industrial Park.
Our core capabilities span two massive product lines: Aromatic Solvents (including S100, S150, S150ND, S180, and S200 series) and Fine Chemical Intermediates. Over the last two decades, we have optimized our supply chains by sourcing refined hydrocarbons directly from industry giants like Sinopec, PetroChina, Hengli Petrochemical, and Zhejiang Petrochemical. This allows us to ensure unmatched quality from initial inputs.
Recognized as a national high-tech enterprise, we pursue process modernization, developing energy-saving manufacturing units and low-VOC solvents. Our domestic supply network supports key operations in major industrial hubs like Beijing, Shanghai, Tianjin, Hebei, and Henan, while our export footprint reaches active chemical distributors and production facilities across the Americas, Europe, Asia, and Southeast Asia.
1,2,4,5-Tetramethylbenzene is utilized across several critical modern manufacturing chains.
Durene serves as the chemical backbone for Pyromellitic Dianhydride (PMDA). PMDA is processed into high-temperature polyimide films, which are critical for flexible printed circuits (FPC), aerospace wire insulation, and semiconductor substrate coatings.
Derivatives of 1,2,4,5-tetramethylbenzene act as non-yellowing, weather-resistant curing components in polyurethane and epoxy formulations. These are widely utilized in heavy-duty automotive, marine, and industrial structural coatings.
Certain halogenated and nitrated derivatives of Durene are critical intermediates for high-selectivity herbicides, crop protection agents, and organic pigments, offering high thermal stability and performance profiles.
At Shandong Saier Chemical, quality control is integrated into every stage of production. Our 1,2,4,5-Tetramethylbenzene is isolated using raw C10 reformate streams from local petrochemical partners. Our process utilizes a specialized combination of:
We accommodate diverse packaging requirements, offering shipments in standard 175kg iron drums, bulk ISO containers, or customized packaging to match our clients' storage facilities and regional safety standards.
Key developments shaping the market for 1,2,4,5-tetramethylbenzene and fine chemical procurement.
Global environmental standards increasingly mandate clean production facilities. Saier Chemical works to decrease operational emissions and run optimized energy-recovery systems, ensuring compliance with strict environmental regulations.
Global buyers are seeking dependable manufacturers to mitigate supply chain disruptions. By maintaining localized feedstocks and robust logistical connections, Saier Chemical provides consistent, year-round product supply for long-term contract agreements.
