2,4-Diaminotoluene; CASRN 95-80-7
Human health assessment information on a chemical substance is included in the IRIS database only after a comprehensive review of toxicity data, as outlined in the IRIS assessment development process. Sections I (Health Hazard Assessments for Noncarcinogenic Effects) and II (Carcinogenicity Assessment for Lifetime Exposure) present the conclusions that were reached during the assessment development process. Supporting information and explanations of the methods used to derive the values given in IRIS are provided in the guidance documents located on the IRIS website.

_I. Chronic Health Hazard Assessments for Noncarcinogenic Effects
_I.A. Reference Dose for Chronic Oral Exposure (RfD)
Substance Name — 2,4-Diaminotoluene
CASRN — 95-80-7
Not available at this time.
_I.B. Reference Concentration for Chronic Inhalation Exposure (RfC)
Substance Name — 2,4-Diaminotoluene
CASRN — 95-80-7
NOTE: This assessment was based on data for 2,4-diaminotoluene, as well as 2,6-diaminotoluene and the mixture. It is intended to be applicable to 2,6- diaminotoluene (CASRN 823-40-5) and the mixture (CASRN 25376-45-8).
The health effects data for diaminotoluene were reviewed by the U.S. EPA RfD/RfC Work Group and determined to be inadequate for derivation of an inhalation RfC. The verification status of this chemical currently is not verifiable. For additional information on health effects of this chemical, interested parties are referred to the EPA documentation listed below.

Agency Work Group Review — 12/18/1990
Screening-Level Literature Review Findings — A screening-level review conducted by an EPA contractor of the more recent toxicology literature pertinent to the RfC for 2,4-Diaminotoluene conducted in September 2002 did not identify any critical new studies. IRIS users who know of important new studies may provide that information to the IRIS Hotline at hotline.iris@epa.gov or (202)566-1676.
