Quality Control

Every batch of 3-Bromo-5-Ethoxy-4-Hydroxybenzaldehyde is produced and tested under a strict quality management system to ensure consistency and reliability for your synthetic processes. Our standard grade typically meets a purity specification of ≥97% (HPLC), with comprehensive identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics. We support custom synthesis and can tailor purity grades (including ≥98% and ≥99%) to meet specific research or cGMP starting material requirements.

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). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere if long-term storage is required to prevent potential degradation.
