DescriptionNANTONG REFORM PETRO-CHEMICAL CO.,LTD, with approximately 203459 visits to its shop, is a reputable Manufactory that has been providing DL-Menthol products for 4 years on ECHEMI.ECHEMI Editorial ReferenceFree-flowing or agglomerated, crystalline powder or prismatic or acicular, colourless, shiny crystals
Racemic menthol is a mixture of equal parts of the (1R,2S,5R)- and (1S,2R,5S)-isomers of menthol. It is a free-flowing or agglomerated crystalline powder, or colorless, prismatic, or acicular shiny crystals, or hexagonal or fused masses with a strong characteristic odor and taste. The crystalline form may change with time owing to sublimation within a closed vessel. The USP 32 specifies that menthol may be either naturally occurring l-menthol or syntheti-cally prepared racemic or dl-menthol. However, the JP XV and PhEur 6.0, along with other pharmacopeias, include two separate monographs for racemic and l-menthol.
Menthol has three asymmetric carbon atoms in its cyclohexane ring and, therefore, occurs as four pairs of optical isomers.The configurations of four of these isomers are given; the other four are their mirror images.(1R,3R,4S)-()-Menthol,,; (1R,3S,4S)-(+)-neomenthol,; (1R,3S,4R)-(+)- isomenthol,; (1R,3R,4R)-(+)-neoisomenthol,. ()-Menthol is the isomer that occurs most widely in nature. It is the main component of peppermint and cornmint oils obtained from the Mentha piperita and Mentha arvensis species. Esterified menthol also occurs in these oils (e.g., as the acetate and isovalerate).Other menthol stereoisomers may be present in these oils as well.
ChEBI: P-menthan-3-ol is any secondary alcohol that is one of the eight possible diastereoisomers of 5-methyl-2-(propan-2-yl)cyclohexan-1-ol. It has a role as a volatile oil component. It is a p-menthane monoterpenoid and a secondary alcohol.
Moderately toxic by ingestion, intraperitoneal, and subcutaneous routes. An eye and skin irritant. K%en heated to decomposition it emits acrid smoke and irritating fumes. See also MENTHOL and 1-MENTHOL.CertificatesBasic Info-

Physical Properties:Physical Properties.The eight optically active menthols differ in their sensory properties. ()-Menthol has a characteristic peppermint odor and also exerts a cooling effect. The other isomers do not possess this cooling effect and are, therefore, not considered to be “refreshing.” Racemic menthol occupies an intermediate position; the cooling effect of the ()-menthol present is distinctly perceptible.The enantiomeric menthols have identical physical properties (apart from their specific rotations), but the racemates differ from the optically active forms in, for example, theirmelting points.Although the differences between the boiling points are small, the (racemic) stereoisomers can be separated by fractional distillation. Boiling points (in °C at 101.3 kPa) are as follows:rac-neomenthol, 211.7rac-neoisomenthol 214.6rac-menthol, 216.5rac-isomenthol, 218.6Other physical constants of commercially available levorotatory and racemic menthols are as follows: ()-menthol, mp 43 °C, [α]20 D 50° (ethanol, 10%); racemic menthol, mp 38 °C.Chemical Properties.Hydrogenation of menthols yields p-menthane; oxidation with chromic acid or catalytic dehydrogenation yields menthones. Dehydration under mild conditions yields 3-p-menthene as the main product. Reaction with carboxylic acids or their derivatives yields menthyl esters, which are used mainly as aroma substances and in pharmaceutical preparations and formulations. The esterification of menthols with benzoic acid is used on an industrial scale in the resolution of racemic menthol.

Toxicity:The acute oral LD50in rats has been reported as 3180 mg/kg by Jenner, Hagan, Taylor, Cook & Fitzhugh (1964) and as 2900 mg/kg by Herken (1961). The acute oral LD50in cats was reported to be 1500-1600 mg/kg (Flury & Seel, 1926). The sc LD50in the mouse was reported as 1400-1600 mg/kg (Flury & Seel, 1926) and the ip LD50as 750 mg/kg in the rat (Herken, 1961) and 1500-1600 mg/kg in the cat (Flury & Seel, 1926). In rabbits, the ip LD50was reported to be approximately 2000 mg/kg (Herken, 1961), while the acute dermal LD50exceeded 5000 mg/kg (Levenstein, 1973).
