Description

3-Cyclopropoxy-4-Hydroxy-Benzaldehyde is a versatile aromatic aldehyde derivative featuring both a phenolic hydroxyl and a cyclopropoxy ether group. This unique bifunctional structure makes it a valuable advanced pharmaceutical intermediate and a key building block in organic synthesis. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Agrochemical Synthesis: Serves as a key building block for developing novel herbicides, fungicides, and insecticides, leveraging its aromatic-aldehyde reactivity.
• Liquid Crystal & OLED Materials: Used in the research and production of advanced electronic display materials due to its rigid, planar aromatic core and functional handles for further modification.
• Organic Synthesis & Research: Employed as a versatile starting material for synthesizing complex heterocycles, ligands for catalysis, and other fine chemicals in academic and industrial laboratories.
• Flavor & Fragrance Ingredient: Acts as a synthetic intermediate for creating specific aromatic aldehydes used in high-value fragrance and flavor compositions.

Quality Control

Our 3-Cyclopropoxy-4-Hydroxy-Benzaldehyde is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency suitable for demanding R&D and scale-up processes. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its sensitivity to light and propensity for oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
