2,6-Dimethylphenol formula graphical representation
2,6-Xylenol; 1-Hydroxy-2,6-dimethylbenzene; 2,6-DMP; 2-Hydroxy-1,3-dimethylbenzene; Phenol, 2,6-dimethyl-; Vic-m-xylenol; Xylenol 235; [ChemIDplus] UN2261
Colorless to off-white solid; [CAMEO] White crystalline powder; [MSDSonline]
Used as an intermediate in organic synthesis; [HSDB]
Irritating to eyes; [HSDB] Safe when used as a flavoring agent in food; [JECFA] Corrosive to tissues; Inhalation may cause laryngeal spasm, edema of the bronchi, and chemical pneumonitis; Chronic exposure may cause liver and kidney damage [CAMEO] Toxic by ingestion, and skin contact; May cause burns; [eChemPortal: ESIS] A corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Inhalation may cause chemical pneumonitis and edema; May be absorbed through skin; Effects in high-dose animal studies include general anesthesia, convulsions or effect on seizure threshold, and impaired liver function; [MSDSonline] "As the six dimethylphenol isomers and the mixed isomer substance are generally similar in toxicity, a common TLV for these substances is appropriate. . . . In mice, oral exposure to 250 mg/kg/day produced changes in blood parameters including statistically significant decreases in mean corpuscular volume and mean corpuscular hemoglobin concentration (4 and 3% reduction in mean values, respectively. . . . Available data on skin sensitization from exposure to dimethylphenol are mixed but warrant the addition of a DSEN notation. . . . All six dimethylphenol isomers were tested in a mouse local lymph node assay and the results found 2.4, 2,5, and 3,4-dimethylphenol to be positive for skin sensitization." There are no epidemiology studies. In a case report, ingestion of about 250 ml of a mixture of dimethylphenol isomers resulted in CNS depression, hypotension, and death. [ACGIH] See "Phenol."
