For chemists, formulators, and procurement specialists in the chemical and F&F industries, a thorough understanding of a compound's properties and safety profile is non-negotiable. 4-Methyl-5-Vinylthiazole (CAS 1759-28-0) is a vital aroma chemical, and grasping its characteristics is essential for its effective and safe utilization. This guide provides insights into its key properties and safety considerations.

Physical and Chemical Characteristics

4-Methyl-5-Vinylthiazole is typically described as a clear liquid, ranging in color from pale yellow to reddish amber. Its molecular formula is C6H7NS, with a molecular weight of approximately 125.19 g/mol. Key physical properties include a flash point around 70-71°C (TCC), indicating it is a combustible liquid. Its density is approximately 1.088-1.099 g/cm³ at 20°C, and its refractive index is around 1.55500-1.57500 at 20°C. While slightly soluble in water, it is generally miscible with common organic solvents used in F&F applications.

The boiling point at atmospheric pressure is approximately 185.3°C, but it is often distilled under vacuum, with a boiling point around 78-80°C at 25 mmHg. It's noted that the compound can slowly decompose at room temperature, hence refrigeration and storage in tightly closed containers, protected from light, are recommended to maintain quality. For buyers, understanding these specifications is crucial when evaluating suppliers and ensuring product integrity.

Safety and Handling Information

Safety is paramount when working with any chemical. While 4-Methyl-5-Vinylthiazole is generally recognized as safe for its intended use in flavors (FEMA GRAS 3313), appropriate handling procedures must be followed. Safety data sheets (SDS) typically indicate that it can be harmful if inhaled, swallowed, or absorbed through the skin. It may also cause irritation to the eyes, respiratory system, and skin. Therefore, when handling this chemical, it is recommended to wear suitable protective clothing, gloves, and eye/face protection. Ensure adequate ventilation and avoid ingestion or direct contact.

Where to Find Reliable Information and Supply

For professionals seeking to buy 4-Methyl-5-Vinylthiazole, it is vital to source from reputable manufacturers and suppliers who provide comprehensive safety data and technical specifications. Companies like NINGBO INNO PHARMCHEM CO.,LTD. offer high-purity 4-Methyl-5-Vinylthiazole and can provide detailed safety information and certificates of analysis. When you search for 'chemical supplier' or 'aroma chemical price,' prioritize those who demonstrate a commitment to transparency and safety, ensuring your procurement process is both efficient and compliant.
