In the business-to-business chemical sector, particularly for intermediates used in pharmaceuticals and advanced research, understanding and verifying product specifications is not just a formality – it's a cornerstone of quality assurance and project success. N-Acetyl-DL-Alanine (CAS 1115-69-1) is one such compound where meticulous attention to purity and physical characteristics is paramount. This article outlines the key specifications that B2B buyers should consider when purchasing this essential chemical intermediate.

The Foundation: Assay and Purity Levels

The primary indicator of a chemical's suitability is its assay, which represents the percentage of the desired compound present. For N-Acetyl-DL-Alanine, a minimum assay of 98.5% is frequently cited. Some sources even indicate purity levels of 97% or 98.0% by HPLC. However, for critical applications such as pharmaceutical synthesis, higher purity is often preferred. An assay range of 98.5% to 101.0% suggests a tightly controlled manufacturing process designed to deliver a high-quality product. B2B buyers should always verify the assay method (e.g., HPLC, titration) and ensure it aligns with their specific application requirements. When sourcing this chemical, asking for detailed lot-specific analysis data or a Certificate of Analysis (CoA) is a standard best practice.

Controlling Impurities: A Closer Look

Beyond the main compound's percentage, the presence and levels of impurities are equally critical. The provided information highlights several key impurity limits for N-Acetyl-DL-Alanine:

  • Loss on Drying: Not more than 0.5%. This indicates the minimal moisture content, important for stability and accurate weighing.
  • Residue on Ignition (as sulfate): Not more than 0.2%. This measures inorganic impurities after combustion.
  • Chloride (Cl): Not more than 0.05%. Low chloride levels are essential, especially in pharmaceutical applications where halide ions can interfere with synthesis or product stability.
  • Heavy Metals (as Pb): Not more than 10ppm. Strict control over heavy metals is a fundamental requirement for any chemical destined for pharmaceutical use, safeguarding against potential toxicity.
  • Iron (Fe): Not more than 10ppm. Iron can act as a catalyst in unwanted side reactions or affect the color of final products.

These parameters collectively define the 'quality' of the N-Acetyl-DL-Alanine. Buyers should look for manufacturers who openly disclose these specifications and can demonstrate consistent adherence to them. If you are looking to buy N-Acetyl-DL-Alanine, understanding these limits will help you assess potential suppliers.

Physical Properties and Handling Considerations

The physical form of N-Acetyl-DL-Alanine is typically described as a white to off-white powder. Its solubility in water is noted as colorless and clear at a concentration of 5%. Melting point data typically falls between 136-139°C. These physical attributes are important for handling, storage, and formulation. For instance, a fine, uniform powder is generally easier to weigh and dissolve accurately compared to clumpy or uneven material. Storage conditions, often recommended at 0-8°C or room temperature, should also be clearly communicated by the supplier to maintain product integrity.

Partnering for Reliable Chemical Supply
