Reactivity Profile
2-(2,4-dinitroanilino)phenol is an organonitrate/phenol. Organonitrate compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups. Phenols do not behave as organic alcohols, as one might guess from the presence of a hydroxyl (-OH) group in their structure. Instead, they react as weak organic acids. Phenols and cresols are much weaker as acids than common carboxylic acids (phenol has Ka = 1.3 x 10^[-10]). These materials are incompatible with strong reducing substances such as hydrides, nitrides, alkali metals, and sulfides. Flammable gas (H2) is often generated, and the heat of the reaction may ignite the gas. Heat is also generated by the acid-base reaction between phenols and bases.
Fire Hazard
Flash point data are not available for 2-(2,4-dinitroanilino)phenol, but 2-(2,4-dinitroanilino)phenol is probably combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 6358-23-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6358-23:
(6*6)+(5*3)+(4*5)+(3*8)+(2*2)+(1*3)=102
102 % 10 = 2
So 6358-23-2 is a valid CAS Registry Number.

Reaction of ethyl 1,4-dihydro-8-hydroxy-4-oxo-3-quinolinecarboxylates XIIIa - XIIIc with 2,4-dinitrochlorobenzene in N,N-dimethylformamide in the presence of sodium hydrogen carbonate yields appropriate ethyl 3-oxo-3H-pyridophenoxazine-2-carboxylates XIVa - XIVc.Similar reaction of XIIIa and XIIIb in aqueous solution yields mixtures of the respective ester (XIVa and XIVb, respectively) and acid (XIVd and XIVe, respectively).Compounds XIVg - XIVj were prepared by usual methods.The compounds prepared were tested for their antimicrobial activity in vitro.
