Pure Transparent 99% CAS 92-06-8 1,3-Diphenylbenzene M-Terphenyl

m-Terphenyl has many applications in the dye industry. It can be used as a synthetic intermediate for dyes, used in the preparation of various pigments and organic dyes. Its pigment properties are stable and widely applied in the fields of pigments, inks, and plastics. m-Terphenyl can also serve as a coating and rubber additive, providing special color effects.

There are various methods for preparing m-Terphenyl, including the Friedel-Crafts reaction and the condensation reaction of aromatic hydrocarbons. Among them, a commonly used method is the synthesis through benzene trimerization, using triphenylmethane (with three benzene rings on the aromatic ring) as the starting material.

It has certain toxicity and irritancy, which may cause harm to the skin, eyes, and respiratory system. Personal protective measures must be taken when handling and using it, such as wearing chemical-resistant gloves, goggles, and masks. Avoid contact with strong oxidizers and strong acids to prevent unsafe chemical reactions. During storage, it should be kept in a cool, dry, and well-ventilated place, away from sources of ignition and combustibles.
