Phenol, 2,3-dimethyl-6-nitro-, also known as 2,3-dimethyl-6-nitrophenol or 2,3-dimethyl-6-nitro-1-hydroxybenzene, is an organic compound with the chemical formula C8H9NO3. It is a derivative of phenol, characterized by the presence of two methyl groups (-CH3) at the 2nd and 3rd carbon positions and a nitro group (-NO2) at the 6th carbon position. This yellow crystalline solid is soluble in organic solvents and has a melting point of approximately 89-91°C. It is primarily used as a chemical intermediate in the synthesis of dyes, pharmaceuticals, and other organic compounds. Due to its reactivity and potential health hazards, it is important to handle Phenol, 2,3-dimethyl-6-nitro- with care, following proper safety protocols.

6665-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6665-95-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6665-95:
(6*6)+(5*6)+(4*6)+(3*5)+(2*9)+(1*5)=128
128 % 10 = 8
So 6665-95-8 is a valid CAS Registry Number.

Preparation of and addition of carbanions to 6-methyl-6-nitrocyclohexa-2,4-dienones

Fischer, Alfred,Henderson, George N.,Sankararaman, S.

, p. 1244 - 1246 (2007/10/02)

Nitration of 2-methylphenols with nitric acid and trifluoroacetic anhydride in ether at -78 deg C gives 6-methyl-6-nitrocyclohexa-2,4-dienones that can be isolated.Carbanions add to 5,6-dimethyl-6-nitrocyclohexa-2,4-dienone to give the 5-substituted 2,3-dimethyl-2-nitrocyclohex-3-enone anion, which, with additional carbanion, gives the 5-substituted 2,3-dimethylphenoxide anion by elimination of nitrous acid.Key words: nitration, dienone, addition, carbanion, nucleophilic.

FORMATION OF DIENONES ON THE REACTION OF CRESOLS, XYLENOLS, AND 2-NAPHTHOL WITH NITROGEN DIOXIDE: OBSERVATION OF KETO TAUTOMERS OF NITROPHENOLS

Fischer, Alfred,Mathivanan, N.

, p. 1869 - 1872 (2007/10/02)

Reaction of o- and p-cresol, the xylenols, and 2-naphthol with nitrogen dioxide gives nitrocyclohexadienones and nitrophenols.Secondary nitrodienones, the keto tautomers of the nitrophenols, have been observed in several cases and are intermediates in the formation of the nitrophenols.

ipso Nitration. XXIV. Nitration of 2-methylphenols. Formation and rearrangement of 6-methyl-6-nitrocyclohexa-2,4-dienones

Cross, Gordon G.,Fischer, Alfred,Henderson, George N.,Smyth, Trevor A.

, p. 1446 - 1451 (2007/10/02)

Nitration of o-cresol and some mono-, di-, and trimethyl derivatives in acetic anhydride at -60 deg C gives 6-methyl-6-nitrocyclohexa-2,4-dienones.The dienones are more labile than the isomeric 4-methyl-4-nitrocyclohexa-2,5-dienones and, if the 2-position of the dienone is not blocked, undergo regiospecific rearrangement to 6-nitro-o-cresols. 2,3,6-Trimethyl- and 2,3,5,6-tetramethylphenol also give a 2,5-dienone with nitro attached to a secondary carbon.
