Quality Control

Every batch of 2-Methyl-1-Pentanethiol is produced and tested under a strict quality management system to ensure consistent purity and performance. Our standard grade typically meets a purity specification of ≥98% (GC), but higher purity grades are available. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. For applications requiring specific regulatory compliance, please contact our technical team to discuss custom specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat sources and open flames. Recommended storage temperature is between 2°C and 25°C. Keep away from strong oxidizing agents and bases. Containers should be kept upright to prevent leakage.
