For any organization involved in chemical synthesis, pharmaceutical development, or advanced biochemical research, the quality of raw materials is a non-negotiable factor. Methionylglycine (H-Met-Gly-OH), identified by CAS number 14486-03-4, is a critical dipeptide that demands stringent quality control throughout its production and supply chain. As a leading manufacturer and supplier, we recognize the imperative for robust quality assurance (QA) and aim to inform our clients about what truly matters when sourcing this compound.

The primary indicator of quality for Methionylglycine is its purity. Typically quantified using High-Performance Liquid Chromatography (HPLC), purity levels of 98% or 99% are generally expected for research and pharmaceutical-grade applications. Impurities, even in trace amounts, can significantly impact reaction kinetics, product yields, and the ultimate performance of synthesized peptides or formulated products. Therefore, buyers should always request a Certificate of Analysis (CoA) that details the purity and the analytical methods used for its determination.

Beyond purity, other critical QA parameters for H-Met-Gly-OH include:

  • Appearance: The product should consistently appear as a white to off-white powder. Variations in color or form can indicate degradation or contamination.
  • Molecular Identity Confirmation: Techniques such as Nuclear Magnetic Resonance (NMR) spectroscopy and Mass Spectrometry (MS) are vital for confirming the correct molecular structure and ensuring it aligns with the expected formula (C7H14N2O3S) and weight (206.26 g/mol).
  • Solubility: Understanding its solubility in common solvents is important for formulation and reaction planning.
  • Storage Conditions: Proper storage recommendations (e.g., at -20°C) are provided to maintain product stability and prevent degradation. Suppliers should adhere to these conditions during transport and handling.

When you decide to buy Methionylglycine, selecting a supplier with a strong QA framework is crucial. This includes having well-defined manufacturing processes, validated analytical methods, and a commitment to traceability through batch numbering. For procurement managers, partnering with a manufacturer that provides comprehensive documentation, such as Safety Data Sheets (SDS), CoAs, and potentially even information on origin, builds confidence and ensures compliance.

As a manufacturer based in China, we pride ourselves on our rigorous quality assurance protocols. Our H-Met-Gly-OH is produced under controlled conditions, with each batch undergoing thorough testing to meet international standards. We offer competitive pricing for bulk quantities, making high-quality Methionylglycine accessible for your critical projects. Understanding these QA aspects empowers you to make informed purchasing decisions and ensures that your research or production processes benefit from the highest quality chemical intermediates.

In conclusion, while price is a factor, the assurance of quality for Methionylglycine (CAS 14486-03-4) should be the primary consideration. A commitment to rigorous quality control by the supplier translates directly into reliable outcomes for your research and development endeavors.
