General Description

Pentadecanoyl chloride, also known as palmitoyl chloride, is a chemical compound commonly used in organic synthesis and industrial applications. It is a derivative of pentadecanoic acid, which is a saturated fatty acid found in palm oil and milk. Pentadecanoyl chloride is a colorless to pale yellow liquid that is highly reactive and can be used as a reagent for acylation reactions. It is often utilized in the production of pharmaceuticals, polymers, and surfactants. Additionally, it can be used as a building block in the synthesis of various organic compounds, such as esters, amides, and complex natural products. However, it should be handled with caution due to its corrosive and irritating properties. Overall, pentadecanoyl chloride plays a crucial role in many chemical and industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 17746-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,4 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17746-08:
(7*1)+(6*7)+(5*7)+(4*4)+(3*6)+(2*0)+(1*8)=126
126 % 10 = 6
So 17746-08-6 is a valid CAS Registry Number.

Characterization of the molecular packing, thermotropic phase behaviour and critical micellar concentration of a homologous series of N-acyltaurines (n = 9–18). PXRD, DSC and fluorescence spectroscopic studies

Arul Prakash, Sukanya,Kamlekar, Ravi Kanth

, (2020/06/22)

N-acyltaurines (NATs) are amides of fatty acids that can be structurally related to endocannabinoids. They show interesting physiological and pharmacological properties. We have synthesized a homologous series of NATs with saturated acyl chains (n = 9–18) and investigated their supramolecular structure and thermotropic phase transitions by powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC). The d-spacings obtained from PXRD increase linearly with chain length with an increment of ~0.847 ? per additional CH2 moiety suggesting that NATs adopt a tilted bilayer structure with similar packing in crystal lattice. Results obtained from DSC studies indicate that the endothermic transition temperature (Tt) of NATs showed a gradually increasing trend with increasing acyl chain length. The enthalpy (ΔHt) and entropy (ΔSt) of transition show odd-even alternations with odd-chain compounds having higher values than the even-chain compounds. The critical micellar concentration (CMC) of NATs was determined in water at room temperature by fluorescence spectroscopy by monitoring the spectral changes of 8-anilinonaphthalene-1-sulfonic acid (ANS). The CMCs of NATs were found to decrease with increase in acyl chain length. The present results provide a thermodynamic and structural basis for investigating the interaction of NATs with other membrane lipids and proteins, which in turn can shed light in understanding how they function in vivo (in biological membranes).

Structure, supramolecular organization and phase behavior of N-acyl-β-alanines: Structural homologues of mammalian brain constituents N-acylglycine and N-acyl-GABA

Sivaramakrishna,Swamy, Musti J.

, p. 1 - 10 (2016/11/11)

N-Acyl-β-alanines (NABAs) are structural homologues of N-acylglycines (NAGs) and N-acyl-γ-aminobutyric acids (NAGABAs), and achiral isomers of N-acylalanines, which are all present in mammalian brain and other tissues and modulate activity of biological receptors with various functions. In the present study, we synthesized and characterized a homologous series of NABAs bearing saturated acyl chains (n = 8-20) and investigated their supramolecular organization and thermotropic phase behavior. In differential scanning calorimetric (DSC) studies, most of the NABAs gave one or two minor transitions before the main chain-melting phase transition in the dry state as well as upon hydration with water, but gave only a single transition when hydrated with buffer (pH 7.6). Transition enthalpies (ΔHt) and entropies (ΔSt), obtained from the DSC studies showed linear dependence on the chain length in the dry state and upon hydration with buffer, whereas odd-even alteration was observed when hydrated with water. The crystal structures of N-lauroyl-β-alanine (NLBA) and N-myristoyl-β-alanine (NMBA) were solved in monoclinic system in the P21/c space group. Both NLBA and NMBA were packed in tilted bilayers with head-to-head (and tail-to-tail) arrangement with tilt angles of 33.28° and 34.42°, respectively. Strong hydrogen bonding interactions between [sbnd]COOH groups of the molecules from opposite leaflets as well as N[sbnd]H?O hydrogen bonds between the amide groups from adjacent molecules in the same leaflet as well as dispersion interactions between the acyl chains stabilize the bilayer structure. The d-spacings calculated from powder X-ray diffraction studies showed odd-even alteration with odd-chain length compounds exhibiting higher values as compared to the even-chain length ones and the tilt angles calculated from the PXRD data are higher for the even chain NABAs. These observations are relevant to developing structure-activity relationships for these amphiphiles and understand how NABAs differ from their homologues and isomers, namely NAGs, NAGABAs, and N-acylalanines.
