Chemical Properties

Clear colorless to light yellowish-brown liquid

Uses

Different sources of media describe the Uses of 112-64-1 differently. You can refer to the following data:
1. It was used in the synthesis of 6-azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose1 and was used in N-acylation of chitosan to introduce hydrophobicity for use as matrix for drug delivery; Myristoyl chloride was used in the synthesis of semi-crystalline dendritic poly(ether-amide) derivatives.
2. Myristoyl chloride was used in the synthesis of 6-azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose. It was used in N-acylation of chitosan to introduce hydrophobicity for use as matrix for drug delivery. It was used in the synthesis of semi-crystalline dendritic poly(ether-amide) derivatives.

Check Digit Verification of cas no

The CAS Registry Mumber 112-64-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112-64:
(5*1)+(4*1)+(3*2)+(2*6)+(1*4)=31
31 % 10 = 1
So 112-64-1 is a valid CAS Registry Number.

Fatty acid-indole fluorescent derivatives as probes to measure the polarity of interfaces containing gangliosides

Bagatolli, Luis A.,Montich, Guillermo G.,Ravera, Mario,Perez, Jorge D.,Fidelio, Gerardo D.

, p. 193 - 202 (1995)

The fluorescence emission properties of three indole derivative probes N-2-(3-indolyl)ethyl-tetradecanoyl carboxamide (N-myrTAM), 2-tetradecanoyl carboxamidyl-3-(3-indolyl)propanoic acid (N-myrTRP) and 11-N(2-[3-indolyl]ethylamino)-9-en-methyloxy carbonyldecenate (11-TAMundec) were studied in solvents of different polarities in pure lysophosphatidylcholine micelles (lysoPC) and in total brain gangliosides (TBG) micelles using steady-state and phase-modulation fluorometry. By comparing the fluorescence emission spectra in solvent mixtures with the spectra in lipid micelles it is concluded that the probes detect a more polar environment in TBG compared to lysoPC micelles. Quenching experiments with acrylamide indicate that the indole group of N-myrTRP and N-myrTAM are more exposed to the aqueous medium than the indole group of 11-TAMundec both in lysoPC and TBG micelles. Quenching of the indole fluorescence with brominated fatty acid at the position 9-10 of the acyl chain is in the following order: 11-TAMundec > N-MyrTAM > N-MyrTRP in lysoPC micelles whereas in TBG micelles only 11-TAMundec fluorescence is quenched. Based on the results of accessibility of the probes to the aqueous quencher and the dielectric constant calculated for their environment, we estimated the surface to core polarity gradient of the micelles. The polarity gradient is higher in TBG micelles compared to lysoPC micelles.

Palladium-Catalyzed H/D Exchange Reaction with 8-Aminoquinoline as the Directing Group: Access to ortho-Selective Deuterated Aromatic Acids and β-Selective Deuterated Aliphatic Acids

Zhao, Donghong,Luo, Haofan,Chen, Binhui,Chen, Wenteng,Zhang, Guolin,Yu, Yongping

, p. 7860 - 7866 (2018)

We develop a palladium-catalyzed H/D exchange reaction with 8-aminoquinoline as the directing group as well as D2O as the source of deuterium atom and solvent. This reaction achieves selectively H/D exchange at the ortho-C-H of aromatic amides and the β-C-H of aliphatic amide. Ortho-deuterated aromatic acids and β-deuterated aliphatic acids are obtained by removal of the directing group. And a possible mechanism is also proposed.

Homologous, long-chain alkyl dendrons form homologous thin films on silver oxide surfaces

Williams, Andre A.,Day, B. Scott,Kite, Brett L.,McPherson, Melinda K.,Slebodnick, Carla,Morris, John R.,Gandour, Richard D.

, p. 5053 - 5055 (2005)

As suggested by X-ray crystal structures, homologous, long-chain alkyl dendrons with three carboxyl groups form thin films on silver oxide surfaces, which give reflection-absorption infrared spectra that show a linear increase in intensities of methylene C-H stretching absorptions.

Synthesis, characterization and mixed micellization study of benzene sulphonate based gemini surfactant with sodium dodecyl sulphate

Wani, Farooq Ahmad,Khan, Abbul Bashar,Alshehri, Abdulmohsen Ali,Malik, Maqsood Ahmad,Ahmad, Rabia,Patel, Rajan

, p. 270 - 278 (2019)

Herein, we have shown the mixed micelle formation between anionic benzene sulphonate (viz., sodium 4,4′-(16,25-dioxo-15,17,24,26-tetraaza-hexatriacontane15,26-diyl)dibenzenesulphonate [BSC14-C6-14CSB]and sodium 4,4′-(18,27-dioxo-17,19,26,28-tetraaza-tetracontane15,26-diyl)dibenzenesulphonate [BSC16-C6-16CSB])with conventional anionic surfactant (sodium dodecyl sulphate [SDS])by conductivity and fluorometry methods. The conductivity measurements were done over a range of mole fractions of SDS at different temperatures to study the mixed micellization and thermodynamic parameters, while fluorescence measurements were performed over entire range of mole fraction of SDS in order to observe the aggregation and micro-polarity. The conductometric study confirms the synergism in all mole fractions of SDS with [BSC14-C6-14CSB]and [BSC16-C6-16CSB]at all temperatures. The Rubinghs regular solution theory (RST)was employed to evaluate micellar mole fraction, X1, ideal micellar mole fraction, Xideal, interaction parameter (β), activity coefficients (f1, and f2)for both mixed micelles systems and Gibbs excess free energy (GE). The GE values are negative for entire mole fraction range suggesting the formation of stable mixed micelles. In addition to this, other thermodynamic parameters like Gibbs free energy change of micellization (ΔGmic), enthalpy change of micellization (ΔHmic)and entropy change of micellization (ΔSmic)were evaluated. Also, the aggregation number (Nagg)in micelles was calculated using pyrene probe fluorescence measurement. The binding constant, dielectric constant and micropolarity of mixed systems of SDS + [BSC14-C6-14CSB]and SDS + [BSC16-C6-16CSB]binary mixtures were obtained from the ratio of peak strength (I1/I3)from the pyrene probe fluorescence emission spectra.

Cationic surfactants with ester groups are considered as an important class of hydrolyzable and biodegradable materials utilized in multiple fields. In this work, a new type of gemini cationic surfactant containing two ester groups, N1,N1,N4,N4-tetramethyl-N1,N4-bis(2-(hexadecanoyloxy)ethyl)butane-1,4-diammonium bromide (TBDB), an 18-4-18 type gemini surfactant, has been successfully synthesized in a three-step reaction from natural palmitic acid, thionyl chloride, N,N-dimethylethanolamine and 1,4-dibromobutane. The maximum yield reaches about 94% under the optimum reaction conditions. The structures of the final product were characterized by FT-IR, 1H NMR and mass spectra. The critical micelle concentration (CMC) and surface tension of its aqueous solution are ~3.09 × 10? 5 M and 38.4 mN/m at 25 °C, respectively, and the gemini ester surfactant shows high benzene solubilization capacity. When treating cotton fabric, it can effectively retain the whiteness and surface hydrophilicity of the fabric while exhibiting a higher fabric-softening ability than the corresponding monomeric surfactants, due to its more efficient adsorption onto the fabric surface. The discovery suggests that this kind gemini ester surfactant is promising with potential applications in the fields of surfactants and coatings.
