Uses
Used in Pharmaceutical Industry:
2-[2-[2-(2-chloroethoxy)ethoxy]ethoxy]ethanol is used as a key component in the synthesis of novel glycolipids for the development of pharmaceutical HIV-1 drugs. These glycolipids have the ability to bind HIV-1 cell surface glycoprotein Gp120, potentially inhibiting the virus's ability to infect host cells and contributing to the fight against HIV-1.
Used in Medical Imaging Industry:
In the field of medical imaging, 2-[2-[2-(2-chloroethoxy)ethoxy]ethoxy]ethanol is utilized in the synthesis of PET (Positron Emission Tomography) imaging agents that specifically target brain β-amyloid. This application is particularly relevant in the diagnosis and monitoring of neurodegenerative diseases, such as Alzheimer's, where the accumulation of β-amyloid plaques is a hallmark feature. By enhancing the imaging of these plaques, this compound aids in the early detection and better understanding of the disease progression.
Check Digit Verification of cas no
The CAS Registry Mumber 5197-66-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5197-66:
(6*5)+(5*1)+(4*9)+(3*7)+(2*6)+(1*6)=110
110 % 10 = 0
So 5197-66-0 is a valid CAS Registry Number.

Difunctional derivatives of bis(m-phenylene)- 32-crown-10
Gibson, Harry W.,Nagvekar, Devdatt S.
, p. 1375 - 1384 (2007/10/03)
Optimization studies of the condensation of methyl 3,5-dihydroxybenzoate (1) with tetra(ethylene glycol) dichloride (3) resulted in improvement of the yield of the 1 + 1 cyclization product, 5-carbomethoxy-m-phenylene-16-crown-5 (5), to 67% (HPLC), but no improvement in the yield (28%, HPLC) of the desired 2+2 product, bis(5-carbomethoxy-m-phenylene)-32-crown-10 (4). However, after optimization, a two-step procedure provided improved yields of 4 and this procedure was generalized to afford other difunctional monomers. Condensation of substituted resorcinols with 3 and subsequent transformations yielded substituted (R) 3,5-bis(11-chloro-3,6,9-trioxaundecyl-oxy)benzenes (7, 9-14). Reaction of dihalides 7 (R = COOCH3), 13 (R = CHO), and 12 (R = CH2OSi(Me)2-t-Bu) with methyl 3,5-dihydroxybenzoate (1) produced bis(5-carbomethoxy-m-phenylene)-32-crown-10 (4) (43%), 5-carbomethoxy-m-phenylene-5′-formyl-m′-phenylene-32-crown-10 (15) (32%), and the lactone (16a) (18%, derived from the initially formed 5-hydroxymethyl-m-phenylene-5′-carbomethoxy-m′-phenylene-32-crown-10 (16)), respectively. Subsequent reactions gave the corresponding diacid (17), bis(hydroxymethyl) (19), bis(bromomethyl) (20), diacetyl (18), diformyl (21), bis(p-nitrophenoxymethyl) (22), and di(acetoxymethyl) (23) derivatives.
