Quality Control

Every batch of 17-Hydroxy-4-Aza-A-Nor-5-Androsten-3-One (4-N,n-Bis(2-Chloroethylamino)Phenyl)Butyrate is manufactured and analyzed under strict quality management protocols. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with research-grade standards and customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
