For procurement professionals and R&D specialists in the chemical industry, identifying reliable sources for key raw materials is paramount. 4-tert-Butylphenol (CAS 98-54-4) is one such compound, a versatile intermediate with a broad range of industrial applications. Whether you require it for resin synthesis, antioxidant formulations, or as a chemical intermediate, securing a high-purity product from a reputable manufacturer is essential. This guide aims to assist buyers in navigating the sourcing process for 4-tert-Butylphenol, focusing on quality, consistency, and supplier reliability, particularly from China, a major global supplier of fine chemicals.

The primary drivers for sourcing high-purity 4-tert-Butylphenol stem from its critical roles in various manufacturing processes. It is extensively used as a chain terminator in the production of polycarbonate resins, ensuring precise molecular weight control. This is vital for applications requiring specific optical and mechanical properties. Additionally, PTBP is a fundamental building block for phenolic and epoxy resins, which are integral to the production of adhesives, coatings, and composite materials. Its utility extends to its function as an antioxidant and stabilizer in plastics and lubricants, safeguarding against degradation and extending product life. Understanding these applications helps in defining the required purity and specifications for your procurement.

When evaluating potential suppliers, quality control and product specifications are non-negotiable. Reputable manufacturers typically offer 4-tert-Butylphenol with an assay of 98% or higher, often characterized by its white to light yellow crystalline flake form. Key parameters to look for in a supplier's technical data sheet include melting point (typically around 96-101 °C), boiling point (236-238 °C), and minimal moisture and ash content. Certificates of Analysis (CoA) are crucial for verifying product quality and batch consistency. Furthermore, inquiring about the supplier's manufacturing capacity, quality management systems (e.g., ISO certifications), and their commitment to environmental and safety standards provides valuable insights into their operational reliability.

The global market for fine chemicals is competitive, and China remains a significant hub for manufacturing and supplying essential chemical intermediates like 4-tert-Butylphenol. Buyers often seek out Chinese manufacturers for their competitive pricing and large-scale production capabilities. When engaging with suppliers, initiating contact for a price inquiry is the first step. Beyond price, consider factors such as lead times for delivery, minimum order quantities (MOQs), and the supplier's responsiveness to queries. Building a strong relationship with a trusted manufacturer or supplier can lead to long-term benefits, including customized solutions and bulk discounts. For businesses aiming to secure a consistent supply of high-purity 4-tert-Butylphenol, a thorough due diligence process, focusing on supplier reputation, product quality, and logistical capabilities, is highly recommended.
