34604-52-9 Usage
Description
Ms-PEG3-Ms are PEG linkers with two mesyl groups. The mesyl groups are good leaving groups and can also be used as protecting groups for primary alcohols. They can be deprotected in the presence of sodium amalgam. The hydrophilic PEG linker increases the water solubility of the compound in aqueous media.
Chemical Properties
White Solid
Uses
Intermediate in the production of alkylating agents
Check Digit Verification of cas no
The CAS Registry Mumber 34604-52-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,0 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 34604-52:
(7*3)+(6*4)+(5*6)+(4*0)+(3*4)+(2*5)+(1*2)=99
99 % 10 = 9
So 34604-52-9 is a valid CAS Registry Number.

MODIFIED CROWN ETHER CATALYSTS. 4. CLEAVAGE OF MACROCYCLIC ETHERS BY EATON'S REAGENT (METHANESULFONIC ACID/PHOSPHORUS PENTOXIDE
Stott, Paul E.,Bradshaw, Jerald S.
, p. 179 - 182 (2007/10/02)
Eaton's reagent (methanesulfonic acid/phosphorous pentoxide) is a superior media for the acylation of benzo crown ether compounds.Benzo-15-crown-5 was cleaved in Eaton's reagent to form methanesulfonate esters of the glycol cleavage products.A comparison of the NMR spectrum of the cleavage products with those of some of the possible products showed that the aliphatic glycols formed the major portion of the cleavage products.
