Health Hazard
Terphenyls are irritants of the
eyes, mucous membranes, and skin.
Flammability and Explosibility
Nonflammable
Safety Profile
Moderately toxic by ingestion. Combustible when exposed to heat or flame. To fight fire, use water, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Potential Exposure
Terphenyl is used primarily as a plasticizer and heat transfer agent. It is also used as a high-temperature lubricant; a constituent of waxes and polishes; as a plasticizer for resinbodied paints; as a coolant and heat storage agent.
Shipping
UN3151 Polyhalogenated biphenyls, liquid or Polyhalogenated terphenyls liquid, Hazard class: 9; Labels: 9-Miscellaneous hazardous material. UN3152 Polyhalogenated biphenyls, solid or Polyhalogenated terphenylssolid, Hazard class: 9; Labels: 9-Miscellaneous hazardous material.
Incompatibilities
Materials are combustible. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides.
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
Check Digit Verification of cas no
The CAS Registry Mumber 26140-60-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,4 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 26140-60:
(7*2)+(6*6)+(5*1)+(4*4)+(3*0)+(2*6)+(1*0)=83
83 % 10 = 3
So 26140-60-3 is a valid CAS Registry Number.
