General Description

(R)-3-Methyl-1-heptanol, also known as (R)-3-methylheptan-1-ol, is a chemical compound with the molecular formula C8H18O. It is classified as an alcohol and is a clear, colorless liquid with a mild, floral odor. (R)-3-METHYL-1-HEPTANOL is used in various industries, including the fragrance and flavor industry, where it is used as a component in perfumes and as a flavoring agent in food products. It is also used as a solvent and in the production of other chemicals. The (R)-3-Methyl-1-heptanol is a chiral compound, meaning it has a non-superimposable mirror image, and the (R)-enantiomer specifically exhibits optical activity. (R)-3-METHYL-1-HEPTANOL has low toxicity and is not considered to be a hazardous substance under normal handling and use.

Check Digit Verification of cas no

The CAS Registry Mumber 99427-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,2 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99427-18:
(7*9)+(6*9)+(5*4)+(4*2)+(3*7)+(2*1)+(1*8)=176
176 % 10 = 6
So 99427-18-6 is a valid CAS Registry Number.

Enantioselective Synthesis of the Sex Pheromone of Lichen Moth, Miltochrista calamine, and Its Diastereomer

Yuan, Gucheng,Liu, Jiawei,Yu, Shihang,Wang, Xueyang,Bian, Qinghua,Wang, Min,Zhong, Jiangchun

supporting information, p. 80 - 83 (2021/10/05)

The synthesis of a Miltochrista calamine sex pheromone and its diastereomer has been developed. The key steps of the synthetic approach involved Evans' chiral auxiliaries and the addition of alkyne to aldehyde, which were firstly applied to prepare this sex pheromone and its diastereomer. The synthetic sex pheromone could be used to trap insects and study physiological and ecological questions of the lichen moth.

Neutral iridium catalysts with chiral phosphine-carboxy ligands for asymmetric hydrogenation of unsaturated carboxylic acids

Yang, Shuang,Che, Wen,Wu, Hui-Ling,Zhu, Shou-Fei,Zhou, Qi-Lin

, p. 1977 - 1980 (2017/03/09)

We developed neutral iridium catalysts with chiral spiro phosphine-carboxy ligands (SpiroCAP) for asymmetric hydrogenation of unsaturated carboxylic acids. Different from the cationic Crabtree-type catalysts, the iridium catalysts with chiral spiro phosphine-carboxy ligands are neutral and do not require the use of a tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (BArF?) counterion, which is necessary for stabilizing cationic Crabtree-type catalysts. Another advantage of the neutral iridium catalysts is that they have high stability and have a long lifetime in air. The new iridium catalysts with chiral spiro phosphine-carboxy ligands exhibit unprecedented high enantioselectivity (up to 99.4% ee) in the asymmetric hydrogenations of various unsaturated carboxylic acids, particularly for 3-alkyl-3-methylenepropionic acids, which are challenging substrates for other chiral catalysts.

Cyclopropanol Methodology in the Synthesis of (4R)- and (4S)-4-Methyltetrahydro-2H-pyran-2-ones. Application in the Synthesis of Insect Pheromones with Methyl-Branched Carbon Skeleton
