2-(2-Nitrophenoxy)biphenyl is an organic compound with the chemical formula C18H13NO3. It is a derivative of biphenyl, which consists of two phenyl rings bonded together, with a nitro group attached to the second phenyl ring and a hydroxyl group attached to the first phenyl ring. 2-(2-nitrophenoxy)biphenyl is known for its potential applications in the synthesis of various pharmaceuticals and agrochemicals, as well as its use as a chemical intermediate. Due to the presence of the nitro group, it may exhibit certain reactivity and should be handled with care, considering its potential hazards and stability.

2688-91-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2688-91-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2688-91:
(6*2)+(5*6)+(4*8)+(3*8)+(2*9)+(1*1)=117
117 % 10 = 7
So 2688-91-7 is a valid CAS Registry Number.

Synthesis of Cycloheptatrienes, Oxepines, Thiepines, and Silepines: A Comparison between Br?nsted Acid and Au-Catalysis

Alcarazo, Manuel,Golz, Christopher,Sprenger, Kristin

, p. 6245 - 6254 (2020)

The cyclization of 1-(benzyl-, oxyaryl-, thioaryl-, and silaaryl)-2-ethynylbenzenes under Br?nsted acid- and Au(I)-catalysis is described. Br?nsted acid catalysis favors without exception the formation of the products derived from the regioselective proto

Synthesis and enantioselective hydrogenation of seven-membered cyclic imines: Substituted dibenzo[b,f][1,4]oxazepines

Gao, Kai,Yu, Chang-Bin,Li, Wei,Zhou, Yong-Gui,Zhang, Xumu

supporting information; experimental part, p. 7845 - 7847 (2011/09/13)

Highly enantioselective hydrogenation of seven-membered cyclic imines, substituted dibenzo[b,f][1,4]oxazepines, was achieved, with up to 94% ee, by using the [Ir(COD)Cl]2/(S)-Xyl-C3*-TunePhos complex as the catalyst in the presence of morpholine-HCl.
