Cashmeran

Cashmeran (trade name; also known as musk indanone or indomuscone; chemical name 6,7-dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone or DPMI) is a chemical compound used in fragrances. Cashmeran (trade name; also known as musk indanone or indomuscone; chemical name 6,7-dihydro-1,1,2,3,3-pentamethyl-4(5H)-indanone or DPMI) is a chemical compound used in fragrances. Cashmeran is an alicyclic ketone with the molecular formula C14H22O and a molecular weight of 206 g/mol. At room temperature it occurs as a white solid but its melting point is 27 °C. Boiling point has been reported to be 256 °C, however in some tests decomposition of the material was noted at 220 °C. Cashmeran was discovered by International Flavors and Fragrances in the 1970s by John Hall. Its invention came about researching inexpensive chemical transformations from ingredients from the pentamethyl indane and tetramethyl naphthalene structures. As a result Cashmeran, an unsaturated ketone, was identified as an important new fragrance ingredient.
