For purchasing professionals in the chemical and pharmaceutical sectors, securing a stable and cost-effective supply of essential raw materials is a strategic imperative. 3-Phenylbutyric Acid (CAS 4593-90-2) is a prime example of such a material, valued for its role as a pharmaceutical intermediate and a versatile building block in fine chemical synthesis. For many global buyers, China represents a primary sourcing destination due to its extensive manufacturing capabilities and competitive pricing. This article outlines key considerations for purchasing managers looking to buy 3-Phenylbutyric Acid from Chinese manufacturers.

The initial step in the procurement process is to identify reputable Chinese manufacturers and suppliers of 3-Phenylbutyric Acid. Look for companies with established certifications, such as ISO, and a proven history of supplying to international markets. Key product specifications to focus on include its chemical formula (C10H12O2), molecular weight (164.2), and, crucially, its purity level. Many applications require 3-Phenylbutyric Acid with a purity of 99% or higher. Always request a detailed Certificate of Analysis (COA) for each batch to confirm that the product meets your exacting standards, including properties like melting point (35-38°C).

When negotiating a purchase, direct inquiries regarding manufacturer pricing for 3-Phenylbutyric Acid are essential for cost optimization. Chinese suppliers often offer tiered pricing based on order volume, making bulk purchases particularly cost-effective. Understanding the payment terms, such as Letter of Credit (L/C) or Telegraphic Transfer (T/T), and Incoterms like FOB or CIF, is critical for managing transaction risks and ensuring smooth logistics. A reliable supplier will also provide clarity on lead times and shipping methods, whether by sea or air.

Building a strong relationship with a chosen supplier is paramount for long-term supply chain stability. Regular communication and transparent dealings foster trust and ensure that any potential issues are addressed promptly. By diligently researching potential partners, verifying product quality, and understanding the nuances of international trade, purchasing managers can successfully buy high-quality 3-Phenylbutyric Acid from China, thereby supporting their organization's production and R&D goals.
