Published 16 June 2025

4-Ethyl-2-methoxyphenol, also known as 4-ethylguaiacol (4-EG), is an organic compound with significant industrial and scientific interest due to its unique chemical structure and functional properties. Belonging to the class of phenols, this compound is characterized by a benzene ring substituted with an ethyl group at the 4-position and a methoxy group at the 2-position. It is known for its aromatic odor, low volatility, and reactivity, making it valuable in a variety of applications, ranging from food and beverage to pharmaceuticals and chemical synthesis.

4 Ethyl 2 Methoxyphenol Market Size was estimated at 1.59 (USD Billion) in 2023. The 4 Ethyl 2 Methoxyphenol Market Industry is expected to grow from 1.67(USD Billion) in 2024 to 2.5 (USD Billion) by 2032. The 4 Ethyl 2 Methoxyphenol Market CAGR (growth rate) is expected to be around 5.16% during the forecast period (2024 - 2032)

Chemical Structure and Properties

The molecular formula of 4-ethyl-2-methoxyphenol is C9H12O2, and its molecular weight is approximately 152.19 g/mol. The presence of both a methoxy (-OCH₃) and a hydroxyl (-OH) group attached to the aromatic ring enhances the molecule’s reactivity and solubility in organic solvents. It appears as a colorless to pale yellow liquid with a spicy, smoky, or clove-like aroma, which is a defining feature of many phenolic compounds.

Key properties include:

  • Boiling Point: ~248 °C
  • Melting Point: Below room temperature
  • Solubility: Soluble in ethanol, ether, and other organic solvents; slightly soluble in water
  • Flash Point: 108 °C

Its odor and flavor characteristics make it particularly important in the context of sensory sciences, especially in food and beverage industries.

Natural Occurrence and Synthesis

4-Ethyl-2-methoxyphenol is naturally found in certain types of wood smoke and roasted foods. It can also be produced by microbial activity, especially by Brettanomyces yeast strains during fermentation, which is why it is sometimes considered a spoilage indicator in beverages like wine and beer.

Industrially, it is synthesized via the methylation of 4-ethylcatechol or via Friedel-Crafts alkylation followed by etherification. The controlled production allows for high purity and consistency, especially critical in flavor and fragrance industries.

Applications

  • Flavor and Fragrance Industry The most prominent application of 4-ethyl-2-methoxyphenol is in the flavor and fragrance industry. It is used as a flavoring agent due to its warm, smoky, and spicy aroma. This compound mimics the flavors found in smoked or roasted foods and is used in small concentrations to impart these desirable sensory notes in sauces, seasonings, and snack products. In perfumery, it adds a deep, balsamic warmth to fragrance compositions, enhancing their complexity and longevity.
  • Food and Beverage Industry In beverages such as wine, beer, and spirits, 4-EG can be both a desirable and undesirable component. When present in low concentrations, it contributes to complex aroma profiles, especially in barrel-aged beverages. However, higher concentrations, often due to contamination by Brettanomyces yeast, can lead to overpowering medicinal or smoky aromas, which are generally considered off-flavors. Hence, its detection is critical in quality control processes in wineries and breweries.
  • Pharmaceutical and Biomedical Uses Phenolic compounds, including 4-ethyl-2-methoxyphenol, have shown antioxidant and antimicrobial properties, making them of interest in pharmaceutical and biomedical research. Preliminary studies suggest that such compounds could be effective in formulations aimed at preventing oxidative stress or microbial infections. However, more research is needed to fully validate its efficacy and safety in medicinal applications.
  • Chemical Intermediate The compound also serves as an intermediate in organic synthesis. Its functional groups make it a useful starting material for the synthesis of more complex molecules used in agrochemicals, dyes, and resins.

Safety and Handling

4-Ethyl-2-methoxyphenol, like many phenolic compounds, must be handled with care. Although it is not classified as highly hazardous, direct contact with skin and eyes should be avoided, and inhalation of vapors should be minimized. In workplace settings, it should be used in well-ventilated areas with appropriate personal protective equipment (PPE). Storage should be in tightly closed containers away from heat and light to prevent degradation.

Market Overview

The market for 4-ethyl-2-methoxyphenol is relatively niche but growing, driven by increasing demand for natural and complex flavor compounds in food and beverages. The shift toward clean-label products and artisanal production methods in the alcoholic beverage industry has brought renewed interest in compounds like 4-EG. The demand for smoky, roasted, and spicy flavor profiles in snack foods and condiments is also a key driver.

In Asia-Pacific, particularly in countries like China, India, and Japan, rising consumer demand for premium and uniquely flavored products is fostering opportunities for flavor and fragrance manufacturers. In North America and Europe, the compound is being studied for its potential functional benefits and used in developing gourmet and craft beverages.

Challenges and Outlook

While demand for 4-ethyl-2-methoxyphenol is increasing, certain challenges remain:

  • Regulatory oversight: Since phenolic compounds can be potent at low concentrations, regulatory approval and monitoring are essential in food applications.
  • Sensory sensitivity: Its potent aroma can dominate formulations if not precisely controlled, necessitating careful dosage and blending.
  • Microbial association: In beverage fermentation, its presence can be a sign of spoilage, which means manufacturers must balance sensory benefits with quality control risks.

Despite these concerns, the outlook for 4-ethyl-2-methoxyphenol remains positive. Its versatility, natural origin, and sensory attributes ensure that it will continue to be an important compound in food, beverage, and fragrance formulations.
