Hazard

A poison. Combustible.

Biochem/physiol Actions

Sodium palmitate is the sodium salt of palmitic acid, a component in hard soaps. Palmitic acid is a common saturated fatty acid and produced during fatty acid synthesis. Sodium palmitate enhances lipogenesis, cellular steatosis in various cell lines. Palmitate induces cell death in human epidermal growth factor receptor 2 (HER2)/neu-positive cells and breast cancer cell lines like MCF-7 due to enhanced fatty acid accumulation. Sodium palmitate induces lipoapoptosis in L02 and HepG2 liver cells by inducing glycogen synthase kinase-3β (GSK3β) expression.

Safety Profile

A poison by intravenous route. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

It crystallises from EtOH and is dried in an oven. [Beilstein 2 IV 1157.]

Check Digit Verification of cas no

The CAS Registry Mumber 408-35-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 408-35:
(5*4)+(4*0)+(3*8)+(2*3)+(1*5)=55
55 % 10 = 5
So 408-35-5 is a valid CAS Registry Number.

Micellar Dynamics and Organization. A Multifield 13C NMR Spin-Lattice Relaxation and /1H/13C Nuclear Overhauser Effect Study

Walderhaug, Harald,Soederman, Olle,Stilbs, Peter

, p. 1655 - 1662 (1984)

An extensive 13C spin-relaxation study is presented for four micellar systems.These are dodecyltrimethylammonium chloride, hexadecyltrimethylammonium chloride, potassium palmitate, and sodium p-octylbenzenesulfonate.The spin relaxation data are analyzed with a relaxation model that takes into account the complexity of molecular motions in surfactant systems.The results show that the internal motions in the micelles are quite fast, occurring on a time scale of 10-11 s, which is similar to that found for liquid hydrocarbons of comparable chain lengths.The motional restrictions imposed by the aggregate-water interface resemble those found in other types of surfactant aggregates.A correlation time associated with the motions of the whole aggregate is extracted.The value of this correlation time implies that, apart from the rotational tumbling and monomer diffusion, the micelles undergo additional motions.

Photolysis of phenacyl esters in a two-phase system

Ruzicka, Radovan,Zabadal, Miroslav,Klan, Petr

, p. 2581 - 2590 (2007/10/03)

Phenacyl esters are useful photoremovable protecting groups for carboxylic acids in organic synthesis and biochemistry. In this work, simple one-pot arrangements of the phenacyl and 2,5-dimethylphenacyl ester photolysis are proposed. The reactions were performed in both the benzene/water two-phase system and in water. Cetyltrimethylammonium bromide was found to increase substantially the efficiency of the deprotection as well as the purity of the products by lowering the interfacial tension between the phases. Utilizing water as a medium significantly reduced the necessity to use environmentally malign organic solvents. The overall yields varied from 72 to 98% depending on the reaction conditions.

Einfluss verschiedener Vorbehandlungen auf die Strukturbildung und thermischen Umwandlungserscheinungen ausgewaehlter Natrium-Seifen

Foerster, G.,Brezesinski, G.,Gerlach, E.,Maedicke, A.,Doerfler, H.-D.

, p. 1009 - 1031 (2007/10/02)

Das thermische Phasenverhalten und die strukturellen Abwandlungen ausgewaehlter Na-Seifen (Na-Kaprylat, Na-Palmitat und Na-Stearat) wurden mit den Methoden der Differential-Scanning-Kalorimetrie, Roentgen- und Elektronenbeugung untersucht.Der Einfluss verschiedener Vorbehandlungen auf die Struktur und thermischen Umwandlungserscheinungen stand im Mittelpunkt des Interesses.Folgende Ergebnisse sind hervorzuheben: 1.Verschiedene Vorbehandlungen (Probenpraeparationen) beeinflussen die Restwassermengen in den Na-Seifen.Zur Herstellung wasserfreier Produkte muss fest gebundenes Wasser (ca. 1/2 mol) unter drastischen Bedingungen entfernt werden. 2.Die Umwandlungstemperaturen und -enthalpien unterschiedlicher Formen obiger Na-Seifen werden angegeben und mit dem Wassergehalt in Beziehung gesetzt. 3.Mit Ausnahme des Kristalls laesst sich der feste Zustand verschieden vorbehandelter Seifen strukturell nicht einheitlich deuten.Die Grenzen bekannter Modellvorstellungen werden diskutiert. 4.Der Kristallzustand laesst sich nur durch Loesungsmittelkristallisation erreichen.Im Kristall sind die Molekuele (NaC18) in einem Gitter der Abmessungen a=9,19 Angstroem und b=8,05 Angstroem gepackt.Die trikline Subzelle TII als Anordnung der aliphatischen Ketten wurde durch Elektronenbeugung an Mikroeinkristallen gesichert.Als Ueberstrukturelemente koennen duenne lamellare Fasern angenommen werden.Eine periodische Anordnung derartiger Fasern ist nachgewiesen worden. 5.Aus den Roentgenbeugungsaufnahmen folgt, dass das Aufschmelzen der Ketten fuer das NaC8, NaC16 und NaC18 einheitlich bei etwa 118 deg C satttfindet und mit einer thermischen Kontraktion und einem Wechsel in der Ueberstruktur verbunden ist.Das Roentgenbeugungsverhalten beim Aufheizen verschiedener Zustaende der Seifen ist jeweils unterschiedlich und konnte nicht in allen Faellen strukturell gedeutet werden.Die Hochtemperaturphasen liessen sich nur beim wasserfreien NaC18 mit dem Modell zentrierter Baenderstrukturen in Uebereinstimmung bringen.
