For chemical manufacturers and product formulators, a deep understanding of an ingredient's chemical profile is fundamental to its successful application. Alpha-Angelica lactone, identified by its CAS number 591-12-8, is a cyclic lactone with a distinct set of chemical and physical properties that make it valuable in various industrial applications, particularly in the flavor and fragrance sectors. This article provides a comprehensive overview of its chemical makeup and physical characteristics, essential knowledge for professionals looking to buy alpha-Angelica lactone.

Alpha-Angelica lactone, with the molecular formula C5H6O2 and a molecular weight of 98.10 g/mol, is also known by synonyms such as 5-Methyl-3H-furan-2-one or alpha-Angelicalactone. It exists as a colorless to light yellow liquid, making it relatively easy to handle and incorporate into liquid formulations. Its physical properties are well-documented: a melting point typically ranging from 13-17°C and a boiling point of 55-56°C at 12 mm Hg. The density is approximately 1.092 g/mL at 25°C, and its refractive index is around 1.448. These parameters are critical for quality control and process optimization. Manufacturers often rely on these precise details to ensure batch-to-batch consistency when they purchase this chemical.

The stability of alpha-Angelica lactone is another key aspect of its chemical profile. While it occurs naturally in sources like tobacco and licorice, its synthesized form is prized for its reliable performance. It exhibits good stability in various pH environments and processing conditions, which is vital for its use in diverse product formulations, from oral care to food flavors. Understanding its chemical reactivity and potential degradation pathways helps formulators predict its behavior and ensure product longevity. When inquiring about this CAS number, potential buyers often seek information on its storage temperature (typically 2-8°C) and its solubility characteristics, such as its moderate solubility in water.

For industries requiring a dependable supply of high-purity alpha-Angelica lactone, partnering with experienced manufacturers is paramount. Suppliers often provide detailed technical data sheets and Certificates of Analysis (CoA) that confirm the chemical's purity (often 98% min.) and adherence to specifications. When looking to purchase alpha-Angelica lactone, understanding its complete chemical profile, from molecular structure to stability and solubility, enables manufacturers to make informed decisions and leverage its unique properties effectively. Engaging with a reputable supplier, such as a leading Chinese manufacturer, can ensure access to both quality material and competitive pricing for this versatile fine chemical.
