Quality Control

Our Pentanenitrile, 2-Ethyl-3-Methyl-4-Oxo-, (R*,S*)- (9Ci) is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment. We support compliance with cGMP and ICH guidelines for pharmaceutical intermediates, and specifications can be aligned with customer-specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from strong bases and incompatible materials such as strong oxidizing agents. Due to its sensitivity to strong alkali/organic solvent conditions as indicated, ensure proper segregation in storage areas.
