The world of fragrances is built upon the intricate chemistry of aroma molecules, each contributing a unique note and character to a scent. 6-Methylcoumarin is one such molecule, a synthetically derived compound widely used in perfumery for its distinctive olfactory qualities. For professionals in the fragrance industry, understanding the precise chemical properties of ingredients like 6-Methylcoumarin is fundamental to effective formulation and product development.

Chemical Structure and Identity

6-Methylcoumarin, with the CAS number 92-48-8 and molecular formula C10H8O2, is a derivative of coumarin. It features a characteristic benzopyrone ring system with a methyl group (-CH3) attached at the sixth carbon atom. This specific molecular arrangement is responsible for its sensory attributes and chemical behavior.

Key Physical and Chemical Properties:

  • Appearance: Typically presented as a white to pale yellow crystalline solid, making it easy to handle and incorporate into formulations.
  • Odor Profile: Known for its sweet, hay-like, and sometimes described as vanilla-like or herbaceous scent. This complex aroma makes it a popular choice for adding warmth and depth to fragrances.
  • Solubility: 6-Methylcoumarin is generally insoluble in water but readily soluble in organic solvents such as ethanol, ethyl acetate, and other common perfume bases. This property is crucial for its incorporation into alcoholic fragrance solutions.
  • Melting Point: It possesses a defined melting point, typically in the range of 73-75°C (or 78-81°C as per some sources), indicating its solid state at room temperature and providing a parameter for quality control.
  • Purity: High-purity grades, often exceeding 99%, are available from reputable suppliers, ensuring consistency and reliability for demanding applications like fine perfumery.
  • Stability: Generally stable under normal storage and usage conditions, which is essential for the longevity and integrity of fragrance compositions.

Significance in Fragrance Formulation

The properties of 6-Methylcoumarin make it a valuable asset for perfumers. Its ability to blend harmoniously with other scent families and its potential role as a fixative, helping to prolong the fragrance’s presence, are particularly noteworthy. When sourcing this ingredient, it is important for buyers to ensure they are obtaining material with consistent quality and purity from reliable chemical manufacturers and suppliers.
