N-methyltaurine

Superior passive stabilised diazo compounds are afforded by the diazoamino compounds (triazenes) that arise by reaction of diazonium salts with a variety of secondary amines [114]. Typically, sarcosine (CH3NHCH2COOH), which gives products based on structure 4.114, as well as N-methyltaurine (CH3NHCH2CH2SO3H) and N methylaniline-4 Sulphonic acid,...

Sodium salt, N-methylaminoethane sodium sulfonute, sodium N-methyltaurate. Usually sold as an aq soln oontg 35% of N-methyltaurine sodium salt. d ° 1.21. At its freezing point (-28° ) the soln becomes a suspension of crystals. Also available as a 65% soln. 

Selectivity differences for the alkane sulfates and sulfonates are not particularly sensitive to changes in the identity of the counterion or the alkyl chain length [204,209]. Sodium dodecyl sulfate is representative of this group. On the other hand, the perflu-orooctanesulfonate and N-alkyl-N-methyltaurine surfactants afford different selectivity to sodium dodecyl sulfate [197,202,208]. Lithium perfluorooctanesulfonate has differ-... 

Figure 8.5. Plot of the system constants (solvation parameter model) against composition for a mixed micelle electrolyte solution containing 50 mM sodium N-dodeconyl-N-methyltaurine and different amounts of the non-ionic surfactant Brij 35 (polyoxyethylene [23] dodecyl ether) (Left). Plot of the system constants for a mixed micelle buffer containing 50 mM sodium N-dodecanoyl-N-methyltaurine and 20 mM Brij 35 against the volume fraction of acetonitrile added to the electrolyte solution (Right). System constants m = difference in cavity formation and dispersion interactions r = difference in electron lone pair interactions s = difference in dipole-type interactions a = difference in hydrogen-bond basicity and b = difference in hydrogen-bond acidity. (From ref. [218] Royal Society of Chemistry).

Concerning sulfur-containing compounds, it is worth mentioning halichondria sulfonic acid, an rmusual derivative of the rare N-methyltaurine and guanidine but already known as a synthetic compormd. This derivative was isolated from the Chinese species Halichondria rugosa. Isolated along with hahstanol sulfate, halichondria sulfonic acid is an HIV-1 inhibitor (Jin et al., 2006). 

A. are made by reaction of fatty acids or their chlorides with N-methyltaurine at 20-30 °C. Aqueous solutions of 40% are obtained, which can be spray-dried to recover a powder.
