p-[2-(4-Quinolyl)vinyl]phenol, also known as 4-[2-(4-hydroxyphenyl)ethenyl]quinoline, is an organic compound with the molecular formula C17H13NO. It is a derivative of quinoline, a heterocyclic compound with a benzene ring fused to a pyridine ring. This particular compound features a vinyl group (C=C) attached to the quinoline ring, and a phenol group (C6H4OH) connected to the vinyl group. The phenol group is located at the para position relative to the vinyl group. This chemical is known for its potential applications in the synthesis of fluorescent dyes and other organic compounds. It is characterized by its unique structure, which combines the properties of both quinoline and phenol, and may exhibit interesting chemical and physical properties due to this combination.

789-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 789-76-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 789-76:
(5*7)+(4*8)+(3*9)+(2*7)+(1*6)=114
114 % 10 = 4
So 789-76-4 is a valid CAS Registry Number.

A recyclable, fluorescent, and colorimetric sensor for fluoride anion in water using a crosslinked polymer functionalized with hydroxyl quinolinium

Tang, Qian,Nie, Hong-Mei,Gong, Cheng-Bin,Liu, Hua-Dong,Xiao, Kun

, p. 3888 - 3893 (2015/02/19)

This study aimed to develop a recyclable, fluorescent, and colorimetric sensor for fluoride anion (F-) in aqueous media with fast response, good selectivity, and high sensitivity. A crosslinked polymer CpA1T5 was designed and synthesized as a sensor using (E)-1-allyl-4-((4-hydroxylphenyl)vinyl) quinolinium bromide as functional monomer, trimethylolpropane trimethacrylate as crosslinker, and azobisisobutyronitrile as initiator. When F- was introduced to the CpA1T5 suspension in deionized water, a change in color from gray to yellow and fluorescence enhancement accompanied with a redshift from 531 nm to 540 nm of fluorescence emission were immediately observed. This F- sensor can be recycled many times, making it cost efficient and beneficial to the environment. Analytical application of CpA1T5 to measure F- concentration in two commercial mouthwash samples was explored with good accuracy.

Visual and reversible detection of cyanide ions in protic solvents by a novel colorimetric receptor

Nie, Hong-Mei,Gong, Cheng-Bin,Tang, Qian,Ma, Xue-Bing,Chow, Cheuk-Fai

, p. 74 - 80 (2014/04/17)

A novel colorimetric chemodosimeter for cyanide (CN-) and 1-allyl-4-[2-(4-hydroxyphenyl)ethenyl)]-quinolinium bromide (AHPEQB) was designed and synthesized by condensation and terminal N alkyl reaction. AHPEQB exhibited highly selective and sensitive recognition properties toward CN - over other competing anions in ethanol, a protic solvent, with a 1:1 binding stoichiometry and a detection limit of 1.7 × 10-6 mol L-1. AHPEQB also displayed rapid colorimetric response that could be readily observed by the naked eye and good reversibility. The sensing mechanism of the proposed chemodosimeter was studied by UV-Vis, 1H NMR titration, and comparison 1-allyl-4-[2-(4-acetoxyphenyl)ethenyl)]- quinolinium bromide (AAPEQB). The colorimetric chemodosimeter showed high accuracy in determining the concentration of CN- in real water samples.
