For chemical engineers, researchers, and product developers, a deep understanding of a compound's chemical properties is foundational to its successful application. DL-Tartaric Acid (CAS: 87-69-4), a vital organic acid, possesses a unique set of characteristics that make it valuable across numerous industries. This article explores the scientific aspects of DL-Tartaric Acid, focusing on its chemical grade and inherent properties that make it a sought-after ingredient.

Chemical Structure and Properties of DL-Tartaric Acid

DL-Tartaric Acid, chemically known as 2,3-dihydroxybutanedioic acid, is a dicarboxylic acid with two hydroxyl groups. Its molecular formula is C4H6O6, and its molecular weight is approximately 150.09 g/mol. It typically presents as a white, crystalline solid. Key physical and chemical properties include:

  • Appearance: Colorless or translucent crystals, or a white, fine granular, crystalline powder.
  • Solubility: It is readily soluble in water and alcohol, a critical feature for many solution-based applications.
  • Melting Point: DL-Tartaric acid has a melting point around 170°C (338°F).
  • Acidity: As a diprotic acid, it contributes to the characteristic sour taste in food products and influences pH levels in various formulations.
  • Chirality: While L-(+)-tartaric acid is the naturally occurring form and is chiral, DL-Tartaric acid is a racemic mixture, meaning it contains equal amounts of the dextrorotatory and levorotatory isomers.

Understanding Chemical Grade and Specifications

The 'chemical grade' of DL-Tartaric Acid refers to its purity and the absence of specific impurities. For applications demanding high quality, such as in food, pharmaceuticals, or specialized chemical synthesis, a high-purity grade is essential. Manufacturers specify parameters like Assay (e.g., 99.7-100.5%), residue on ignition, heavy metals, and specific ion content (chloride, sulfate, etc.). Ensuring that the DL-Tartaric Acid you purchase meets these specifications is crucial for the performance and safety of your final product. When you buy DL-Tartaric Acid, always request a detailed Certificate of Analysis (CoA) from your DL-Tartaric Acid supplier.

Sourcing High-Purity DL-Tartaric Acid

For businesses in need of this chemical, identifying a reputable DL-Tartaric Acid manufacturer in China is often the most effective strategy for securing both quality and competitive pricing. Companies that specialize in producing high-purity grades, like Ningbo Innopharmchem, ensure that their product adheres to stringent international standards. Whether you are seeking it for food applications or industrial chemical synthesis, a dependable food grade tartaric acid supplier or an industrial chemical provider is your best resource.

By understanding the scientific basis of DL-Tartaric Acid's properties and the importance of its chemical grade, procurement managers and product developers can make informed decisions. Partnering with expert manufacturers ensures access to high-quality materials, supporting innovation and product excellence.
