For procurement managers and R&D scientists, understanding the critical specifications and quality assurance protocols for chemicals like D-2-Aminoadipic Acid (CAS 7620-28-2) is fundamental to making informed purchasing decisions. This compound, recognized for its properties as a glutamine synthetase inhibitor, is vital for numerous biochemical and pharmaceutical applications.
The primary specification to consider when you buy D-2-Aminoadipic Acid is its purity, which is typically guaranteed at 97% or higher. This ensures that the product meets the stringent requirements for scientific research and pharmaceutical manufacturing. Beyond assay, other key physical and chemical properties include its appearance, which is usually a white to off-white powder or crystalline powder. Specific rotation values, such as -23°±2°, and melting points, around 205-210°C, are also important indicators of product quality and consistency.
Quality assurance from a D-2-Aminoadipic Acid supplier is a multi-faceted aspect. It begins with rigorous raw material selection and extends through meticulous manufacturing processes. Reputable manufacturers will provide comprehensive documentation, including Certificates of Analysis (CoA) with each batch, detailing all critical parameters and confirming adherence to specifications. This documentation is crucial for regulatory compliance and scientific validation.
When sourcing D-2-Aminoadipic Acid, especially from an international D-2-Aminoadipic Acid manufacturer, it is advisable to inquire about their quality management systems, such as ISO certifications. Understanding their storage and handling procedures also assures that the product's integrity is maintained from production to delivery. Companies that prioritize transparency in their quality control measures build trust with their clients.
For businesses needing to purchase D-2-Aminoadipic Acid, partnering with a supplier that emphasizes quality assurance provides peace of mind. Whether for use as a biochemical reagent or a pharmaceutical intermediate, consistent quality is non-negotiable. Requesting detailed specifications and inquiring about the supplier's quality assurance practices will help you secure a reliable source for this important chemical compound.
