Quality Control

Our Propanal, 2-Phenoxy-, (S)- (9Ci) is produced under strict quality management systems to ensure batch-to-batch consistency and high enantiomeric purity. We provide comprehensive analytical data including Chiral HPLC for enantiomeric excess (ee) determination and standard identity/purity tests. A detailed Certificate of Analysis (COA) is supplied with each batch, documenting compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This compound is easily oxidized and light-sensitive; allow the container to reach room temperature before opening to minimize moisture ingress and degradation.
