For procurement specialists and researchers in the chemical and pharmaceutical industries, identifying trustworthy suppliers for essential chemical intermediates is a critical task. 3-Methylphenylacetic Acid, known by its CAS number 621-36-3, is a compound that plays a vital role in various synthesis processes. This guide is designed to assist buyers in locating and purchasing this intermediate from reliable manufacturers and suppliers within China, a leading global hub for chemical production.

Understanding 3-Methylphenylacetic Acid: Properties and Uses

3-Methylphenylacetic Acid is typically encountered as a white to light beige powder. Its chemical identity is characterized by the formula C9H10O2 and a molecular weight of approximately 150.17. This organic acid is valued for its versatility as a chemical intermediate, serving as a building block in the synthesis of pharmaceuticals and other fine chemicals. A notable application is its use as a reactant in the diastereoselective preparation of arylmethylene-isoindolinones, highlighting its importance in advanced organic chemistry.

When sourcing this compound, buyers often look for high purity, commonly specified at 99%, to ensure optimal performance in their applications. Availability in various quantities, from research-scale grams to industrial-scale kilograms and tons, is also a key consideration.

Key Factors When Buying from China

China's extensive chemical manufacturing infrastructure offers a wide array of options for sourcing 3-Methylphenylacetic Acid (CAS 621-36-3). To ensure a successful procurement, consider the following:

  • Manufacturer vs. Trader: Prioritize sourcing directly from manufacturers to ensure consistent quality, better pricing, and greater transparency. Manufacturers are equipped with the production facilities and quality control systems necessary for reliable output.
  • Verification and Credentials: Look for suppliers who can provide essential documentation such as Certificates of Analysis (COA), Material Safety Data Sheets (MSDS), and proof of quality certifications (e.g., ISO).
  • Communication and Responsiveness: Effective communication is key. Choose suppliers who are responsive to inquiries regarding product specifications, pricing, minimum order quantities (MOQ), and shipping arrangements.
  • Payment and Shipping Terms: Clearly understand the payment terms (e.g., T/T, L/C) and shipping options (e.g., FOB, CIF) to manage your logistics and costs effectively.
  • Reputation and Track Record: Research potential suppliers, read reviews if available, and consider their experience in exporting chemicals to your region.
