Description

Cohumulone CAS NO 511-25-1 is a key alpha acid isomer found in the resin of hop plants (Humulus lupulus). This compound is of significant commercial interest due to its direct impact on the bitterness profile, foam stability, and antimicrobial properties of beer. It is an essential raw material for brewers, flavor chemists, and researchers focused on beverage science and natural product extraction. Precise control over cohumulone content allows for the fine-tuning of final product characteristics in the brewing and related industries.

Application

• Brewing Industry: Primary use as a bittering agent and foam stabilizer in beer production. The ratio of cohumulone to other alpha acids influences the quality and character of beer bitterness.
• Hop Extract Production: A critical component in the manufacture of standardized hop extracts and isomerized pellets for consistent brewing results.
• Flavor & Fragrance: Serves as a precursor and reference standard for developing and analyzing hop-derived flavors in foods and beverages.
• Phytochemical Research: Used as a high-purity analytical standard in laboratories studying the chemistry and bioactivity of hop constituents.
• Quality Control: Employed as a calibration standard in HPLC and other analytical methods to ensure the quality and authenticity of hop products.
• Natural Product Isolation: A target compound for extraction and purification processes in the nutraceutical and botanical ingredient sectors.
