| RCRA-Anforderungen | U222As stipulated in 40 CFR 261.33, when o-toluidine hydrochloride, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5). |

| Environmental Biodegradation | Thirty-eight process wastewaters and 37 organic substances identified in the wastewater of the Kashima petrochemical complex were subjected to the activated sludge degradability test. The test used the activated sludge of the Fukashiba industrial wastewater treatment plant, which was acclimatized to the wastewater and organic substances. Water in the test container was sampled during aeration at 0 hr and 24 hr later. After 1 day of acclimation, 100 mg/l of 2-methylaniline resulted in a chemical oxygen demand (Mn) of 92% and 83% total organic carbon. /2-methylaniline/ |

| Evidence for Carcinogenicity | The Human Health Assessment Group in EPA's Office of Health and Environmental Assessment has evaluated o-toluidine hydrochloride for carcinogenicity. According to their analysis, the weight-of-evidence for o-toluidine hydrochloride is group B2, which is based on inadequate evidence in humans and sufficient evidence in animals. As a group B2 chemical, o-toluidine hydrochloride is considered to be probably carcinogenic to humans.Classification of carcinogenicity: 1) evidence in humans: insufficient2) evidence in animals: sufficient. Overall summary evaluation of carcinogenic risk to humans is Group 2B: The agent is possibly carcinogenic to humans. /From tableortho-Toluidine/A3Confirmed animal carcinogen with unknown relevance to humans. /o-Toluidine/o-Toluidine Hydrochloride: reasonably anticipated to be human carcinogens. /o-Toluidine and o-Toluidine Hydrochloride/ |

Verwenden
o-Toluidine and o-toluidine hydrochloride are used primarily as intermediates in the manufacture of more than 90 dyes and pigments (NCI 1979, IARC 1982, 2000). They are used in acid-fast dyestuffs, azo pigments and dyes, triarylmethane dyes, sulfur dyes, and indigo compounds and as a photographic dye. o-Toluidine is also used as an intermediate for synthetic rubber and rubber vulcanizing chemicals, pharmaceuticals, and pesticides and as a curing agent in epoxy resin systems. Other minor uses of o-toluidine and its hydrochloride salt are as an intermediate in organic synthesis and as an ingredient in a clinical laboratory reagent for glucose and hemoglobin analyses.
