Stability of Dodecylbenzene (CAS No.123-01-3): Stable. Incompatible with strong oxidizing agents. Combustible.
1-Phenyldodecane (CAS No.123-01-3) was brought to market after SRI (Stanford Research Institute) did scientific and business consulting work on it in 1948 for Chevron. Dodecyl benzene was the basis for the first successful household detergent, Tide.
As a liquid aromatic compound, Dodecylbenzene (CAS No.123-01-3) is used to prepare an anionic detergent dodecylbenzene sodium sulfonate. It is a petrochemical-derived substitute for the tallow and coconut oil used in making soap.

Dodecylbenzene (CAS No.123-01-3), it also can be called Tetrapropylenebenzene ; Benzene, dodecyl- ; Dodecane, 1-phenyl- ; Dodecane, 1-phenyl- (8CI) ; Dodecane, phenyl- .It is colorless liquid with a weak oily odor, and it can floats on water.It will causes mild irritation of eyes and may cause allergenic responses on repeated contact with skin, and if Ingestion will causes nausea. Dodecylbenzene (CAS No.123-01-3) can cause vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Dodecylbenzene , and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
