Quality Control

Our 4-Chloro-3-Methylbut-2-En-1-Ol is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chromatography and spectroscopy, to confirm identity and purity. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request, supporting compliance with cGMP and other relevant industry standards for fine chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or an opaque secondary container until use.
