Quality Control

Every batch of 3-Chloro-2-(Methylsulfanyl)Benzaldehyde is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, is performed to verify identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, and custom purity grades (e.g., >97%, >98%, >99%) are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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 amber glass until use.
