1R,4R-p-mentha-2,8-dienol, also known as (1R,4R)-(-)-p-mentha-2,8-dien-1-ol or commonly referred to as neomenthol, is a naturally occurring monoterpene alcohol derived from the essential oil of peppermint (Mentha piperita). It is a chiral compound with a molecular formula of C10H18O and a molecular weight of 154.25 g/mol. Neomenthol is an isomer of menthol, differing in the configuration of its chiral centers. It exhibits a cooling sensation similar to menthol but is less potent and less widely used in commercial applications. Neomenthol is primarily used in the fragrance and flavor industries, as well as in some pharmaceutical applications. Its chemical structure consists of a cyclohexane ring with two double bonds and a hydroxyl group, giving it unique properties and applications in various fields.
The CAS Registry Mumber 3186-77-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,8 and 6 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3186-77: (6*3)+(5*1)+(4*8)+(3*6)+(2*7)+(1*7)=94 94 % 10 = 4 So 3186-77-4 is a valid CAS Registry Number.
