For procurement managers and R&D scientists in the chemical and related industries, sourcing the right raw materials is paramount. Methylsuccinic Acid (CAS 498-21-5) is a fine chemical intermediate with significant applications, particularly in the fragrance and food sectors. Understanding how to effectively source this compound from reliable manufacturers and suppliers in China can significantly impact cost-efficiency and product quality.

Methylsuccinic Acid, also known by its IUPAC name Methylbutanedioic acid or Pyrotartaric acid, is a white solid with the molecular formula C5H8O4. Its utility stems from its dicarboxylic acid structure, making it a valuable building block in organic synthesis. The demand for high-purity Methylsuccinic Acid is driven by its role as an intermediate in the production of dyes and fragrances, as well as its application as a food additive for preservation and flavoring.

When looking to buy Methylsuccinic Acid, B2B buyers should prioritize purity levels, often specified by standards like USP, BP, or FCC. A typical specification for high-quality Methylsuccinic Acid is a purity of ≥99%. Manufacturers will often provide Certificates of Analysis (CoA) detailing lot-specific data, including purity and melting point (typically around 110-115°C). Ensuring you receive this documentation is crucial for quality assurance.

The price of Methylsuccinic Acid can vary based on purity, order volume, and supplier. As a general guideline, prices can range from $0-99/kg FOB China. To get the most accurate pricing, it is advisable to directly contact multiple suppliers and manufacturers, request quotes, and potentially negotiate bulk purchase agreements. Factors such as minimum order quantities (often around 25kg) should also be considered.

Identifying a dependable supplier or manufacturer in China is key to a stable supply chain. Look for companies with established manufacturing sites, adherence to quality management systems (like ISO certifications), and a track record of reliable service. Engaging with suppliers for samples before placing large orders is a standard practice to verify product quality and suitability for your specific application. For those seeking to purchase Methylsuccinic Acid, reaching out to reputable manufacturers who can provide technical data sheets (TDS) and safety data sheets (SDS) is essential.

By focusing on these aspects – purity, price, and supplier reliability – procurement professionals can confidently source Methylsuccinic Acid (CAS 498-21-5) to meet their production and development needs. Direct inquiries to manufacturers in China are the most effective way to secure this vital chemical intermediate.
