Geosmin, cataloged under CAS number 19700-21-1, is a sesquiterpenoid alcohol celebrated for its characteristic potent earthy odor. This molecule is not merely an olfactory curiosity; it is a key player in environmental science, water quality management, and even the food industry. Understanding the science behind Geosmin is vital for professionals who deal with its detection or utilize it for its unique sensory properties. As a leading manufacturer and supplier, we provide high-purity Geosmin essential for such endeavors.

The production of Geosmin is primarily biological. It is synthesized by various microorganisms, including certain species of actinobacteria (like Streptomyces) and cyanobacteria. These microbes produce Geosmin as a secondary metabolite. Its release into the environment, particularly into water sources, is often triggered by changes in microbial population dynamics or environmental conditions. This natural production pathway means that Geosmin can appear unexpectedly in water supplies, leading to sensory complaints from consumers.

The odor threshold of Geosmin is remarkably low, often measured in parts per trillion. This extreme sensitivity means that even minuscule amounts can dramatically impact the perceived quality of water or food. In drinking water, Geosmin is the principal compound responsible for the undesirable earthy and musty flavors and aromas. Consequently, accurate detection and quantification methods are indispensable for water treatment plants. Techniques such as Gas Chromatography-Mass Spectrometry (GC-MS) are commonly employed, requiring certified reference standards like the high-purity Geosmin (CAS 19700-21-1) that we manufacture and supply.

For those in the flavor and fragrance sector, Geosmin's distinct earthy profile is a valuable ingredient. It can be used to impart authentic, natural notes reminiscent of soil, root vegetables, or damp earth into food products and perfumes. The ability to buy precisely characterized Geosmin allows flavorists and perfumers to achieve desired sensory outcomes consistently.

Scientific research continues to explore Geosmin's ecological roles, including its potential function in attracting certain insects for spore dispersal or guiding the migration of aquatic organisms. As a dedicated supplier, we ensure that researchers have access to reliable Geosmin to conduct these investigations. Our commitment as a manufacturer in China to producing high-purity Geosmin at competitive prices underscores our dedication to supporting scientific advancement and industrial applications worldwide. If you need to buy Geosmin for your laboratory or production needs, rely on a manufacturer with a proven track record of quality and consistency.
