Description
Octadecanamide, a fatty amide of stearic acid, is a metabolite derived from octadecanoic acid. It appears as white or light yellow granules, turning into colorless leafy crystals after recrystallization in ethanol. Octadecanamide is soluble in hot ethanol, chloroform, and ether, but insoluble in cold ethanol and water. It has lower lubricity than grease, shorter continuity, and poor thermal stability, which can be improved with a small amount of advanced alcohol (C16 ~ 18).
Uses
Used in Oil and Gas Industry:
Octadecanamide is used as a corrosion inhibitor in oil wells to prevent the corrosion of pipelines and equipment, ensuring the smooth operation of oil extraction processes.
Used in Cosmetics Industry:
Octadecanamide is used as an emollient and viscosity-increasing agent in cosmetic formulations, providing a smooth texture and improving the product's performance on the skin.
Used in Lubricants:
Due to its lower lubricity compared to grease, Octadecanamide can be used in the formulation of lubricants to provide a balance between lubrication and other desired properties, such as viscosity and thermal stability.
Used in Pharmaceutical Industry:
Octadecanamide can be used as an excipient in pharmaceutical formulations, contributing to the stability and performance of the final product.
Used in Food Industry:
Octadecanamide can be used as an additive in the food industry to improve the texture and stability of certain products, such as baked goods and confectionery.

Check Digit Verification of cas no
The CAS Registry Mumber 124-26-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 4 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 124-26:
(5*1)+(4*2)+(3*4)+(2*2)+(1*6)=35
35 % 10 = 5
So 124-26-5 is a valid CAS Registry Number.

Selective Transformations of Triglycerides into Fatty Amines, Amides, and Nitriles by using Heterogeneous Catalysis

The use of triglycerides as an important class of biomass is an effective strategy to realize a more sustainable society. Herein, three heterogeneous catalytic methods are reported for the selective one-pot transformation of triglycerides into value-added chemicals: i) the reductive amination of triglycerides into fatty amines with aqueous NH3 under H2 promoted by ZrO2-supported Pt clusters; ii) the amidation of triglycerides under gaseous NH3 catalyzed by high-silica H-beta (Hβ) zeolite at 180 °C; iii) the Hβ-promoted synthesis of nitriles from triglycerides and gaseous NH3 at 220 °C. These methods are widely applicable to the transformation of various triglycerides (C4–C18 skeletons) into the corresponding amines, amides, and nitriles.
Metal-Free Thermal Activation of Molecular Oxygen Enabled Direct α-CH2-Oxygenation of Free Amines

Direct oxidation of α-CH2 group of free amines is hard to achieve due to the higher reactivity of amine moiety. Therefore, oxidation of amines involves the use of sophisticated metallic reagents/catalyst in the presence or absence of hazardous oxidants under sensitive reaction conditions. A novel method for direct C-H oxygenation of aliphatic amines through a metal-free activation of molecular oxygen has been developed. Both activated and unactivated free amines were oxygenated efficiently to provide a wide variety of amides (primary, secondary) and lactams under operationally simple conditions without the aid of metallic reagents and toxic oxidants. The method has been applied to the synthesis of highly functionalized amide-containing medicinal drugs, such as O-Me-alibendol and -buclosamide.
