Quality Control

Every batch of 5-(sec-Butyl)-2-Methoxybenzaldehyde 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, and NMR, is performed to verify identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

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 sensitivity to light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
