Reactivity Profile
A nitrated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
Health Hazard
ACUTE/CHRONIC HAZARDS: When heated to decomposition 3-nitrofluoren-9-one emits toxic fumes.
Fire Hazard
Flash point data for 3-nitrofluoren-9-one are not available. 3-nitrofluoren-9-one is probably combustible.
Check Digit Verification of cas no
The CAS Registry Mumber 42135-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,3 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42135-22:
(7*4)+(6*2)+(5*1)+(4*3)+(3*5)+(2*2)+(1*2)=78
78 % 10 = 8
So 42135-22-8 is a valid CAS Registry Number.

supporting information, p. 236 - 245 (2018/12/11)
Palladium catalyzed domino C-H functionalization reaction of arylaldehyde with dihaloarene has been developed to access 9-flourenone molecules. Bidentate ligand assisted strategy, single step reaction, high yield and excellent functional group tolerance make this method concise and effective for the synthesis of 9-flourenone. In addition, proposed method has been successfully employed to synthesise Tilorone in gram scale.
