In the B2B chemical sector, particularly for ingredients destined for food and fragrance applications, quality assurance is not just a protocol – it's a guarantee of safety and product integrity. For 2,3-Pentanedione (CAS 600-14-6), often referred to as acetyl propionyl, understanding these quality metrics is crucial for procurement managers and R&D specialists. This guide aims to inform buyers on what to look for when sourcing this key flavor and fragrance intermediate from a reliable manufacturer in China.

Key Quality Specifications for 2,3-Pentanedione

When you intend to buy 2,3-Pentanedione, the first specification to scrutinize is its purity. Typically, a minimum purity of 97% is expected for applications in flavors and fragrances. This is usually determined through Gas Chromatography (GC) analysis. High purity ensures that the characteristic creamy, buttery aroma is consistent and free from unwanted off-notes that could arise from impurities.

Beyond purity, other critical quality indicators include:

  • Appearance: The product should be a clear, yellow-green oily liquid. Any deviation in color or clarity might indicate contamination or degradation.
  • Odor: A characteristic creamy, buttery, and slightly sweet quinone-like smell is expected. Diluted samples should exhibit a distinct creamy aroma.
  • Melting Point: Recorded at -52°C, this is a physical characteristic that confirms the chemical identity.
  • Boiling Point: Typically around 110-112°C, this parameter is also important for identity verification and understanding its volatility.

Ensuring Supplier Reliability and Compliance

As a buyer seeking a dependable 2,3-Pentanedione supplier, verifying the manufacturer's commitment to quality is paramount. Look for suppliers who:

  • Provide a comprehensive Certificate of Analysis (CoA) with each batch, detailing all critical quality parameters.
  • Hold relevant certifications, such as ISO 9001, which demonstrates a robust quality management system.
  • Have transparent manufacturing processes and are willing to share information on their quality control measures.
  • Offer readily accessible Safety Data Sheets (SDS) and Technical Data Sheets (TDS) that comply with international standards.

Regulatory Approvals and Safety

For food applications, regulatory compliance is non-negotiable. 2,3-Pentanedione is listed and permitted as a food flavor in China under GB 2760-86. Buyers should confirm that the product sourced meets the standards of their target markets, whether it's FCC (Food Chemicals Codex) listed or complies with FDA and EFSA regulations in other regions. The safety profile, including toxicity data (e.g., LD50 values) and handling precautions, should be clearly communicated by the acetyl propionyl manufacturer.

Cost-Effectiveness Without Compromising Quality

Sourcing from China can offer significant cost advantages, allowing for a more competitive 2,3-Pentanedione price. However, it's crucial to balance cost with quality. By focusing on suppliers who prioritize stringent quality control and transparency, buyers can ensure they receive a product that meets their demanding application requirements. Engaging with an established 2,3-Pentanedione manufacturer that understands international quality expectations is the key to successful procurement.
