2163-11-3 Usage

Description

THP-PEG3 is a PEG chain linker with a THP alcohol protecting group. The THP can be removed under acidic conditions. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media.

Chemical Properties

Colourless Oil

Uses

Tetrahydropyranyldiethyleneglycol (cas# 2163-11-3) is a compound useful in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 2163-11-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2163-11:
(6*2)+(5*1)+(4*6)+(3*3)+(2*1)+(1*1)=53
53 % 10 = 3
So 2163-11-3 is a valid CAS Registry Number.

Formation of mono- and di-nuclear complexes of Zn2+ from a 26 membered tetraester crown of 3,5-disubstituted pyrazole able to act as neutral and dianionic ligand

Acerete, Carmen,Bueno, Jose M.,Campayo, Lucrecia,Navarro, Pilar,Isabel Rodriguez-Franco,Samat, Andre

, p. 4765 - 4774 (1994)

A selective synthesis of bis(3,5-diketo-1H-pyrazole)-[26]crown- 12 (1, L1) has been performed. Its deprotonation pKa values, and those of the acyclic analogues (3-5) have been measured. The disodium dipyrazolate salt of 1 (2, [L2]2- 2Na+) has been isolated, and mono- and di- nuclear complexes of Zn2+ obtained from 1 ([L1Zn]2+) and 2 ([L2Zn2]2+) have been studied by 13C NMR spectroscopy in DMSO-d6 solution.

Synthesis and assembly of novel poly(organophosphazene) structures based on noncovalent "host-guest" inclusion complexation

Tian, Zhicheng,Chen, Chen,Allcock, Harry R.

, p. 1065 - 1072 (2014)

The design and assembly of new organophosphazene polymeric materials based on supramolecular "host-guest" interactions was accomplished by linkage of supramolecular coupling units to either the main-chain terminus or the side-chains of the parent phosphazene polymer. Noncovalent interactions at the main chain terminus were used to produce amphiphilic palm-Tree like pseudoblock copolymers via host-guest interactions between an adamantane end-functionalized polyphosphazene and a 4-armed β-cyclodextrin (β-CD) initiated poly[poly(ethylene glycol) methyl ether methacylate] branched-star type polymer. Moreover, noncovalent interactions involving polymer side-chains were achieved between polyphosphazenes with β-CD pendant units and other polyphosphazene molecules with adamantyl moieties on the side-chains. These new organo-phosphazene structures based on noncovalent "host-guest" interactions generate new opportunities for the macromolecular modification of polyphosphazenes. The resultant materials demonstrated useful properties including self-aggregation, supramolecular gelation, and stimulus-responsive behavior.

P-stereogenic diphosphacrowns: Facile incorporation of aromatic rings

Kato, Ryosuke,Watanabe, Hiroyuki,Morisaki, Yasuhiro,Chujo, Yoshiki

, (2016/03/01)

P-Stereogenic diphosphacrowns containing naphthalene and pyridine rings were synthesized. Facile incorporation of aromatic rings, and chains of different lengths, into the diphosphacrown skeleton was achieved by altering the electrophile in our previously
