Sulfurol, identified by its CAS number 137-00-8, stands as a crucial component in the world of food flavors and fragrances. This distinctive compound, also known by names such as 4-Methyl-5-thiazoleethanol or 2-(4-Methyl-5-thiazolyl)-ethanol, plays a significant role in creating complex and appealing aroma profiles, particularly those associated with savory and cooked notes. Its molecular formula, C6H9NOS, and molecular weight of 143.21 define its chemical structure, contributing to its unique sensory characteristics. As a high-purity ingredient, Sulfurol is essential for flavorists aiming to achieve precise and consistent results in their formulations.

Physically, Sulfurol typically presents as a colorless to light yellow viscous oily liquid. While freshly produced material maintains a clear appearance, it can darken over time upon long storage, a factor important for handling and shelf life considerations. Its aroma is perhaps its most defining feature. Described as having a cooked beef gravy-like fatty aroma, it also possesses, when highly diluted, a distinct nutty note. This duality makes it incredibly versatile, capable of contributing both depth and nuance to flavor compositions. It exhibits good solubility characteristics, being easily soluble in water and soluble in organic solvents like ethanol, ether, and benzene, which facilitates its incorporation into various product matrices.

The primary application of Sulfurol is as an edible flavor or flavor enhancer, functioning as both a natural equivalent flavor and an artificial flavor depending on its source and context. Its savory, meaty notes are particularly valued in applications involving roasted foods, meat products, and nuts. In roasted food applications, Sulfurol can enhance the desirable aromas developed during cooking processes, providing authenticity and richness. For meat systems, it helps to build or boost the characteristic savory, umami-like profiles that consumers find appealing. Similarly, in nut-based flavors, its subtle nutty undertones, revealed upon dilution, can add layers of complexity.

Beyond its prominent role in food and beverage flavoring, Sulfurol also finds utility in other fine chemical industries. The base material can be applicable in fragrance compositions, although its primary strength lies in savory flavor creation. Its potential extends to being used as a reagent or intermediate in the synthesis of other compounds, highlighting its value as a versatile fine chemical. The pharmaceutical industry also represents a potential area for its use, perhaps as a building block or for specific research purposes, although its main commercial footprint is firmly in the flavor and fragrance sector.

Achieving high purity is paramount for Sulfurol used in food applications. Purity levels, typically standardized at 99%, ensure the desired aroma characteristics are delivered without off-notes that could detract from the final product's quality. Rigorous quality control measures are essential, encompassing analysis for content, physical and chemical properties, and ensuring absence of contaminants. The stability of Sulfurol can be improved with stabilizers, and proper storage in cool, dry, light-free conditions in sealed containers, often under nitrogen, is crucial to maintain its quality over its shelf life, typically around two years when stored correctly.

The demand for sophisticated and authentic savory flavors continues to grow in the global food market. Ingredients like Sulfurol are indispensable for flavor houses and food manufacturers seeking to develop innovative and highly palatable products. Understanding the specific properties and optimal usage levels of Sulfurol is key to unlocking its full potential in flavor creation. As with any specialty ingredient, reliable sourcing is critical. Companies looking to buy Sulfurol CAS 137-00-8 or needing a consistent supplier must consider factors like purity, manufacturing standards, and logistics.

The market for high-quality flavor ingredients is competitive, and securing the right manufacturer is vital for ensuring supply chain stability and product consistency. While price is always a consideration, the value of Sulfurol lies in its potent flavor impact, allowing for lower usage rates compared to less effective alternatives. Bulk purchase options typically offer more favorable pricing structures, making it economical for large-scale flavor production. Whether you are formulating complex meat seasonings, enhancing roasted snacks, or developing unique savory profiles, Sulfurol offers a powerful tool in the flavorist's palette. Sourcing high-purity Sulfurol from a trusted manufacturer and supplier is the first step towards leveraging its unique capabilities to create winning food flavors.
