Description
(-)-MONO-(1R)-MENTHYL PHTHALATE is a chemical compound that is commonly used as a fragrance ingredient in various cosmetic and personal care products. It is a clear liquid with a strong, fresh, and slightly floral odor, and it is known for its ability to impart a long-lasting and pleasant scent to products.
Used in Cosmetic and Personal Care Industry:
(-)-MONO-(1R)-MENTHYL PHTHALATE is used as a fragrance ingredient for its ability to impart a long-lasting and pleasant scent to products.
Used in Plastics and Resins Industry:
(-)-MONO-(1R)-MENTHYL PHTHALATE is used as a plasticizer in the production of plastics and resins.
However, its use has raised concerns due to its potential to act as an endocrine disruptor and its ability to bioaccumulate in the environment. As a result, there have been restrictions on its use in certain countries and a push for alternative, safer ingredients in consumer products.
Check Digit Verification of cas no
The CAS Registry Mumber 33744-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33744-74:
(7*3)+(6*3)+(5*7)+(4*4)+(3*4)+(2*7)+(1*4)=120
120 % 10 = 0
So 33744-74-0 is a valid CAS Registry Number.

Diastereoselective Synthesis of Thioglycosides via Pd-Catalyzed Allylic Rearrangement

Stereoselective glycosylation is challenging in carbohydrate chemistry. Herein, stereoselective thioglycosylation of glycals via palladium-catalyzed allylic rearrangement yields various substituents on α-isomer thioglycosides. Two comprehensive series of aryl and benzyl thioglycosides were obtained via a combination of thiosulfates with glycals derived from glucose, arabinose, galactose, and rhamnose. Furthermore, diosgenyl α-l-rhamnoside and isoquercitrin achieved selectivity via stereospecific [2,3]-sigma rearrangements of α-sulfoxide-rhamnoside and α-sulfoxide-glucoside, respectively.
Asymmetric rhodium carbene insertion into the Si-H bond: Identification of new dirhodium(II) carboxylate catalysts using parallel synthesis techniques

Decomposition of methyl 2-diazophenylacetate in the presence of silanes and a chiral dirhodium(II) catalyst results in Si-H insertion of the intermediate carbenoid with varying degrees of enantioselectivity. New chiral dirhodium(II) carboxylate catalysts were identified using solution phase parallel synthesis techniques.
