Import 3, 5- Di-Tert-Butylphenol Cas:1138-52-9 — Buy in Bulk from Supplier in China

3,5-Di-tert-butylphenol (CAS 1138-52-9) is a hindered phenolic compound with the molecular formula C14H22O and a molecular weight of 206.33 g/mol. This white to off-white crystalline solid features two tert-butyl groups at the 3 and 5 positions of the phenol ring, which confer exceptional steric hindrance and thermal stability. The compound is supplied by Liaoning Cured Medical Technology Co., Ltd. from their facility in Panjin, Liaoning Province, China, with packaging typically in 25 kg drums or custom configurations to preserve stability during transit and storage.

The material serves primarily as an antioxidant and stabiliser in polymer systems, particularly in polyolefins, synthetic rubbers, and lubricating oils. Its hindered phenolic structure allows it to scavenge free radicals efficiently, interrupting oxidative degradation chains at elevated temperatures. Typical purity for industrial grades exceeds 99.0%, with melting points in the range of 87-91 degrees Celsius. Storage at cool, dry conditions away from oxidising agents is standard practice; the phenolic hydroxyl group renders it mildly acidic and susceptible to degradation under strongly basic conditions. In rubber compounding, it functions as a non-staining antioxidant, a critical advantage over amine-based alternatives that discolour finished products.

Buyers in plastics processing, tyre manufacturing, and industrial lubricant formulation represent the core demand for this material. The compound's thermal stability makes it suitable for high-temperature processing environments where less robust antioxidants would volatilise or decompose. When sourcing from this supplier, confirm the exact purity specification, certificate of analysis availability, and whether the material is supplied as flakes, powder, or prills, as physical form affects handling and dissolution in masterbatch preparation. The supplier's location in Panjin, a petrochemical hub in northeastern China, offers access to raw material infrastructure, though buyers should verify current production capacity and export licensing status directly.

Liaoning Cured Medical Technology Co., Ltd. operates from Shuangtaizi Industry Park A19 in Panjin, Liaoning Province, China. The company is classified at the harbor trust tier, indicating a baseline verification status on the platform. The response rate stands at 0.00% with an average response time of 0 hours, which suggests either a newly registered profile, limited active engagement, or data capture issues rather than a definitive operational assessment. Buyers should treat initial inquiries as exploratory and follow up through multiple channels to establish direct communication.

The company name references medical technology, yet the listing covers an industrial antioxidant chemical, a common pattern among Chinese chemical traders who handle multiple product segments under a single corporate entity. No verified ISO, SGS, or other third-party certifications are confirmed in the source data, and any claims to such should be requested as current copies during due diligence. The Panjin location places the supplier within a significant petrochemical processing region in northeastern China, with access to port facilities at Yingkou or Dalian for export shipments. Buyers should independently verify manufacturing versus trading status, as the company may source from third-party producers rather than manufacture the phenol derivative directly.
