2,4,7-トリニトロ-9-フルオレノン (約20% 水湿潤品)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

SMALL SPILLS AND LEAKAGE: If a spill of this chemical occurs, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with acetone and transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

2,4,7-TRINITRO-9-FLUORENONE INDUCED BOTH FRAMESHIFT MUTATIONS & BASE-PAIR SUBSTITUTIONS IN SALMONELLA TYPHIMURIUM STRAINS TA100, TA98, TA1537 & TA1538. COMPARISONS OF MUTAGENIC POTENCY SUGGEST IMPORTANCE OF CARBONYL GROUP SUBSTITUTED AT THE CARBON-9 POSITION OF MUTAGENIC DERIV.

NITRATED DERIVATIVES OF FLUORENE ARE POTENT FRAMESHIFT-TYPE MUTAGENS. REDN OF NITRO FUNCTION IS REQUIRED FOR EXPRESSION OF MUTAGENICITY. HYDROXYLAMINES ARE PRESUMED KEY INTERMEDIATES, WHICH FOLLOWING ESTERIFICATION TO ELECTROPHILS ARE CAPABLE OF FORMING ADDUCTS WITH CELLULAR DNA.

2,4,7-TRINITRO-9H-FLUOREN-9-ONE IS MUTAGENIC IN SALMONELLA TYPHIMURIUM/MICROSOMAL ASSAY WITH & WITHOUT S9 METABOLISM. IT IS PRIMARILY A FRAMESHIFT MUTAGEN. IT IS ALSO MUTAGENIC IN MOUSE LYMPHOMA ASSAY & CHINESE HAMSTER OVARY CELLS.
