Description
3-Ethylcatechol is a versatile organic compound belonging to the catechol family, featuring an ethyl substituent that modifies its reactivity and solubility profile. This compound serves as a valuable chemical intermediate and building block in the synthesis of more complex molecules. It is particularly sought after by industries involved in pharmaceutical development, agrochemical formulation, and specialty polymer production.
Application
- Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those with catechol-based structures for neurological and cardiovascular applications.
- Agrochemical Synthesis: Serves as a key precursor in the manufacture of herbicides, fungicides, and plant growth regulators.
- Polymer & Resin Modifier: Acts as a monomer or additive in the production of specialty polymers, epoxy resins, and antioxidants to enhance material properties.
- Flavor & Fragrance Ingredient: Employed as a synthetic intermediate for creating specific smoky or spicy aroma chemicals.
- Photographic Chemicals: Used in the formulation of certain developers and other photo-sensitive materials.
- Research & Development: A valuable reagent in organic chemistry research for studying oxidation reactions and synthesizing novel heterocyclic compounds.

Quality Control
Our 3-Ethylcatechol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality commitment supports applications requiring high-purity intermediates.
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). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
