Uses
Hexaethylene glycol monodecyl ether is a nonionic surfactant useful for proteomics research.
Definition
detergent: A substance added towater to improve its cleaning properties.Although water is a powerfulsolvent for many compounds, it willnot dissolve grease and natural oils.Detergents are compounds that causesuch nonpolar substances to go intosolution in water. Soap is the originalexample, owing its action tothe presence of ions formed fromlong-chain fatty acids (e.g. theoctadecanoate (stearate) ion,CH3(CH2)16COO-). These have twoparts: a nonpolar part (the hydrocarbonchain), which attaches to thegrease; and a polar part (the –COO–group), which is attracted to thewater. A disadvantage of soap is thatit forms a scum with hard water (seehardness of water) and is relativelyexpensive to make. Various synthetic(‘soapless’) detergents have been developedfrom petrochemicals. Thecommonest, used in washing powders,is sodium dodecylbenzenesulphonate,which containsCH3(CH2)11C6H4SO2O- ions. This, likesoap, is an example of an anionic detergent,i.e. one in which the activepart is a negative ion. Cationic detergentshave a long hydrocarbonchain connected to a positive ion.Usually they are amine salts, as inCH3(CH2)15N(CH3)3+Br-, in which thepolar part is the N(CH3)3+ group.Nonionic detergents have nonionicpolar groups of the type–C2H4–O–C2H4–OH, which formhydrogen bonds with the water.Synthetic detergents are also used aswetting agents, emulsifiers, and stabilizersfor foam.
Check Digit Verification of cas no
The CAS Registry Mumber 5168-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5168-89:
(6*5)+(5*1)+(4*6)+(3*8)+(2*8)+(1*9)=108
108 % 10 = 8
So 5168-89-8 is a valid CAS Registry Number.
