Specification
2,6-Dichlorophenol , its cas register number 87-65-0. It also can be called 2,6-Dichlorfenol [Czech] ; 2,6-Dichlorophenol ; BRN 1447806 ; CCRIS 2511 ; HSDB 4240 ; NSC 60647 ; and Phenol, 2,6-dichloro- . Its classification code are Skin / Eye Irritant and TSCA Flag T [Subject to the Section 4 test rule under TSCA].
2,6-Dichlorophenol (CAS NO.87-65-0) is stable. It should avoid the condition like incompatible materials. It is not compatible with incompatible materials, acid chlorides, acid anhydrides. And also prevent it to broken down into hazardous decomposition products: hydrogen chloride, carbon monoxide, carbon dioxide. However, its hazardous polymerization will not occur.
