Quality Control

Our 1-Phthalazinethiol is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques, including HPLC, GC, and NMR, to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and during sampling to maintain stability.
