Product Description
Musk Ketone, CAS 81-14-1, is a synthetic nitro musk compound known for its sweet, persistent, slightly animalic musk odor. Also called Ketone Musk or Ketone Moschus, it has historically been used in perfumery to create warm, powdery fragrance effects and support the lasting character of selected perfume accords.
The compound has a molecular formula of C₁₄H₁₈N₂O₅ and a molecular weight of approximately 294.30 g/mol. It is typically described as a yellow or light-yellow crystalline solid and is practically insoluble in water. These characteristics should be considered when evaluating storage conditions, handling procedures, and compatibility with fragrance bases.
Musk Ketone belongs to the nitro musk family. Its use is subject to important regulatory and environmental considerations, and its historical presence in fragrance products does not mean it is permitted for every current application or market. Before purchasing, buyers should confirm the intended use, destination-market requirements, and any applicable fragrance-industry standards.
For quality assessment, request a current Technical Data Sheet (TDS), Safety Data Sheet (SDS), and batch-specific Certificate of Analysis (COA). Check the assay, appearance, melting range, impurity profile, and any relevant limits for other nitro musk compounds, including musk xylene.
