Description

3-Ethyl-5-Methylbenzenemethanol CAS NO 244080-18-0 is a versatile aromatic alcohol derivative, serving as a critical chiral intermediate and building block in advanced organic synthesis. Its value lies in the functional benzylic alcohol group and substituted ethyl/methyl pattern, which enables precise molecular construction for high-value fine chemicals. This compound is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty materials sectors seeking to develop novel active ingredients and performance additives.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in central nervous system (CNS) and anti-inflammatory drug candidates.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators, leveraging its aromatic structure for bioactivity.
• Liquid Crystal & OLED Materials: Serves as a precursor for mesogens and charge-transport materials in display and lighting technologies due to its stable, substituted benzene core.
• Fragrance & Flavor Chemistry: Acts as an intermediate for synthesizing specific musky or woody aroma chemicals where the ethyl and methyl substitutions modify scent profiles.
• Polymer Modification: Employed as a chain terminator or functional monomer to introduce hydroxyl groups into polymers, enhancing adhesion, cross-linking, or compatibility.
• Organic Synthesis Reagent: A valuable starting material or protecting group precursor in multi-step synthetic routes for academic and industrial research laboratories.

Quality Control

Our 3-Ethyl-5-Methylbenzenemethanol is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and NMR/IR for structural confirmation, to ensure it meets the high standards required for fine chemical synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance support for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to 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 flames.
