Geosmin, identified by the CAS number 19700-21-1, is a potent organic compound renowned for its distinct earthy aroma. This sesquiterpenoid is naturally produced by various microorganisms, most notably actinobacteria and cyanobacteria. Its presence is directly linked to the characteristic smell of freshly tilled soil after rain, a phenomenon often referred to as petrichor. For professionals in the environmental and food industries, understanding Geosmin is crucial due to its significant impact on sensory perception.
The olfactory detection threshold for Geosmin is exceptionally low, meaning even minute concentrations can be perceived by the human nose. This sensitivity makes it a primary culprit behind taste and odor issues in municipal drinking water supplies. When populations of geosmin-producing bacteria bloom and then decline, they release substantial amounts of this compound into the water, leading to complaints about musty or earthy flavors and smells. This necessitates reliable analytical methods and high-quality standards for effective monitoring and remediation.
As a leading manufacturer and supplier of fine chemicals, we specialize in providing high-purity Geosmin (CAS 19700-21-1) for a variety of applications. Our product is indispensable for water treatment facilities aiming to detect and quantify geosmin contamination, ensuring the delivery of palatable drinking water. Researchers in environmental science and microbiology utilize our Geosmin as a reference standard to study the metabolic pathways of odor-producing microbes and their ecological roles.
Furthermore, the flavor and fragrance industry leverages Geosmin to recreate authentic earthy notes in food products, such as root vegetables like beets, or to develop specific scent profiles in perfumes. The ability to buy high-purity Geosmin from a trusted manufacturer in China ensures consistency and quality for these specialized applications. We pride ourselves on offering competitive pricing and ensuring supply chain stability for our clients worldwide.
For procurement managers and research scientists seeking a reliable source for Geosmin, consider partnering with experienced suppliers who prioritize quality control and provide comprehensive technical support. Engaging with a reputable manufacturer ensures you receive a product that meets rigorous specifications, facilitating accurate analysis and innovative product development. Invest in quality Geosmin to address environmental challenges and enhance sensory experiences.
