In analytical chemistry, precision and reliability are paramount. The accuracy of chromatographic separations and mass spectrometric identifications hinges on the quality of the standards used. L-Norleucine (CAS 327-57-1), a non-proteinogenic amino acid, serves as an invaluable analytical standard in various laboratory settings. NINGBO INNO PHARMCHEM CO.,LTD., a premier manufacturer and supplier of fine chemicals from China, offers high-purity L-Norleucine that meets the exacting demands of analytical applications.

L-Norleucine as a Crucial Analytical Standard

The application of L-Norleucine in analytical chemistry stems from its well-defined structure and chemical properties. It is particularly utilized for:

  • Internal Standards in Mass Spectrometry: L-Norleucine can be added to samples as an internal standard to accurately quantify other compounds, especially amino acids or related metabolites, by compensating for variations in sample preparation and ionization efficiency.
  • Chromatographic Method Development: Researchers use L-Norleucine to develop and validate methods for High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC), ensuring proper separation and detection of amino acids.
  • Quality Control of Biological Samples: In the analysis of biological fluids or protein hydrolysates, L-Norleucine helps in identifying and quantifying specific amino acid components, contributing to accurate quality control.
  • Research in Protein Structure: Its use in studying protein folding and stability also relies on analytical techniques where L-Norleucine acts as a marker or a comparative standard.

Ensuring Analytical Accuracy with High-Purity L-Norleucine

For any analytical application, the purity of the standard is critical. Impurities can lead to inaccurate results, compromising the integrity of the research or quality assessment. NINGBO INNO PHARMCHEM CO.,LTD. understands this necessity and is committed to supplying L-Norleucine with a purity of ≥99%. Our rigorous manufacturing processes and quality assurance protocols ensure that each batch delivers the consistency and reliability required for precise analytical work. As a direct manufacturer in China, we offer competitive pricing and accessible sampling, making it easier for laboratories worldwide to buy the quality materials they need.
