Description

Tos-PEG5-CH2CO2t-butyl ester, also known as Tos-PEG5-CH2CO2tBu, is a PEG (polyethylene glycol) linker that features a t-butyl ester and a tosyl group. This molecule is designed to enhance solubility in aqueous media due to the hydrophilic PEG spacer. The t-butyl protected carboxyl group can be deprotected under acidic conditions, allowing for further chemical modifications or reactions. The tosyl group serves as an excellent leaving group for nucleophilic substitution reactions, making it a versatile component in various chemical and biological applications.

Uses

The PEG linker can be incorporated into polymers, hydrogels, or other materials to improve their hydrophilicity, biocompatibility, and responsiveness to environmental stimuli.
Used in Analytical Chemistry:
Tos-PEG5-CH2CO2t-butyl ester is used as a reagent in analytical chemistry for the modification of surfaces or the development of new chromatographic stationary phases. The PEG linker can provide improved separation and detection of various analytes, while the t-butyl ester and tosyl group can be used for immobilization or further functionalization.

Check Digit Verification of cas no

The CAS Registry Mumber 169751-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,7,5 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 169751-73:
(8*1)+(7*6)+(6*9)+(5*7)+(4*5)+(3*1)+(2*7)+(1*3)=179
179 % 10 = 9
So 169751-73-9 is a valid CAS Registry Number.
