2697-42-9

MeOPN, or methyl para-nitrophenol, is an organic compound with the chemical formula C7H7NO3. It is a derivative of phenol, where a methyl group (-CH3) is attached to the para position (the fourth carbon) and a nitro group (-NO2) is attached to the same carbon. MeOPN is a yellow crystalline solid that is soluble in organic solvents and has a melting point of approximately 85°C. It is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and dyes. Due to its reactivity and potential health hazards, MeOPN is handled with caution and is subject to strict safety regulations in its production and use.

2697-42-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2697-42-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,9 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2697-42:
(6*2)+(5*6)+(4*9)+(3*7)+(2*4)+(1*2)=109
109 % 10 = 9
So 2697-42-9 is a valid CAS Registry Number.

Nucleophilic Reactions of Anions with Trimethyl Phosphate in the Gas Phase by Ion Cyclotron Resonance Spectroscopy

Hodges, Ronald V.,Sullivan, S. A.,Beauchamp, J. L.

, p. 935 - 938 (2007/10/02)

The gas-phase ion-molecule reactions of several negative ions (SF6-, SF5-, SO2F-, F2-, F-, CF3Cl-, Cl-, CD3O-, DNO-, OH-, and NH2-) with trimethyl phosphate are investigated using ion cyclotron resonance techniques.Nucleophilic attack on OP(OCH3)3 occurs chiefly at carbon, resulting in displacement of O2P(OCH3)2-.This behavior contrast with that observed in solution, where attack at phosphorus is favored for hard nucleophiles.This difference is ascribed to solvation energetics for the intermediates involved in the two reactions.The failure of SF6- to transfer F- to OP(OCH3)3 places an upper limit of 11 +/- 8 kcal/mol on the fluoride affinity of OP(OCH3)3.The significance of the results for the negative chemical ionization mass spectrometry of phosphorus esters is briefly discussed.

SOLVOLYSIS OF DIPHENYL AMIDOPHOSPHATES IN AQUEOUS ALCOHOLIC MEDIA

Kasparek, Frantisek,Mollin, Jiri

, p. 386 - 396 (2007/10/02)

Influence of substituent on the reaction rate of the alkali-catalyzed solvolysis of the studied compounds set has been followed.The activation entropy has also been determined.The reaction products have been identified, and their concentration ratio has been determined.The reaction selectivity is mostly influenced by sterical effects in the substrate molecule.The results obtained agree with the SN2 mechanism.
