Navigating the landscape of chemical sourcing requires a keen understanding of product specifications, especially when procuring specialized compounds like 3-Bromo-L-phenylalanine (CAS: 82311-69-1). For researchers, formulators, and procurement specialists, knowing what to look for ensures that the intermediate purchased will perform optimally in its intended application, whether it's pharmaceutical synthesis, peptide construction, or advanced biochemical studies. As a premier manufacturer and supplier, we aim to provide clarity on these critical details.

What is 3-Bromo-L-phenylalanine?

3-Bromo-L-phenylalanine is a derivative of the amino acid phenylalanine. Its chemical structure features a bromine atom substitution on the phenyl ring, which alters its electronic and steric properties. This modification makes it a valuable tool for synthetic chemists, enabling the creation of more complex and functionalized molecules.

Key Specifications to Consider When You Buy

When you decide to purchase 3-Bromo-L-phenylalanine, paying close attention to the following specifications is crucial:

  • CAS Number: The Chemical Abstracts Service (CAS) registry number, 82311-69-1, is a unique identifier ensuring you are sourcing the correct chemical compound.
  • Purity: This is arguably the most critical specification. For applications in pharmaceutical development and sophisticated peptide synthesis, high purity is essential. Manufacturers typically specify purity as determined by High-Performance Liquid Chromatography (HPLC). Aim for products with purity levels of 98% or higher. Lower purity can lead to unwanted side reactions, reduced yields, and compromised results.
  • Appearance: The physical form of the product is important for handling and initial assessment. 3-Bromo-L-phenylalanine is typically supplied as a solid, often described as a powder. Common descriptions include 'Grey powder' or 'Off-white powder'. Significant deviations from this can indicate contamination or degradation.
  • Molecular Formula and Weight: C9H10BrNO2, with a molecular weight of approximately 244.09 g/mol, are fundamental identifiers. Ensure these match your requirements.
  • Optical Rotation: As an L-amino acid derivative, its optical rotation ([α]²⁰D) is a key indicator of its enantiomeric purity. A specification like '+5° (c=4 in 1N NaOH)' or similar is common and vital for chiral synthesis applications.
  • Melting Point: The melting point range provides another measure of purity. For example, a range like '227-232 °C' indicates a relatively pure compound.
  • Solubility: While not always listed as a primary spec, understanding its solubility in common solvents (e.g., slightly soluble in water) is helpful for application preparation.

Why Buy from a Direct Manufacturer in China?
