Quality Control

Every batch of 1-(Thien-3-Ylmethyl)-1H-Pyrazol-5-Amine is manufactured and tested under a strict Quality Management System. We provide comprehensive analytical documentation, including a Certificate of Analysis (COA) with detailed HPLC/GC purity data, identity confirmation (IR, NMR), and impurity profiles to ensure compliance with your project specifications. Our quality commitment supports applications requiring GMP-grade intermediates and materials for regulatory filings.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat and incompatible materials.
