4	Skin sensitization	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
5	Germ cell mutagenicity	Category 1B	Danger	H340	P308+P313 P201 P202 P280 P405 P501	There are positive results from in vivo somatic cell mutagenicity tests including bone marrow or peripheral blood micronucleus tests by oral gavage to mice (NTP DB (2004)), bone marrow chromosomal aberration test by intraperitoneal injection to mice (NTP DB (1983)) and erythrocyte micronucleus test by oral gavage and intraperitoneal injection to 2 mouse strains (HSDB (2000)). In addition, there is a report that the frequency of dominant lethal mutations increases with higher dose levels in mice (in vivo heritable germ cell mutagenicity test) (HSDB (2000)). Based on these results, the substance was classified into Category 1B. As relevant information, from in vitro mutagenicity tests, there are reports of a positive Ames test and a positive CHO cell chromosomal aberration test (NTP DB (1982, 1987)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
6	Carcinogenicity	Category 2	Warning	H351	P308+P313 P201 P202 P280 P405 P501	Based on the classification of "Group 2B" in IARC (IARC suppl. 7 (1987)), the substance was classified into Category 2. As relevant information, the substance is classified into "R" in NTP (NTP RoC (11th, 1983)). The substance is reported to be carcinogenic in mice and rats and produce mainly lung and kidney tumours following subcutaneous or intraperitoneal injections (IARC 7 (1974)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
7	Reproductive toxicity	Category 2	Warning	H361	P308+P313 P201 P202 P280 P405 P501	In a test where male rats administered by gavage for 5 days and mated to untreated females, effects on male fertility index and reduction in number of implants are reported (RTECS (2008): TXAPA9 Toxicology and Applied Pharmacology. 70 (1983)). Information on resorbed implants, fetal death and growth restriction are reported separately (RTECS (2008): JTSCDR Journal of Toxicological Sciences. 25 (2000)). In a similar test in mice, effects on male fertility index and death of offspring (RTECS (2008): JACTDZ Journal of the American College of Toxicology. 2 (2) (1983)) were reported. In addition, there are report that intraperitoneal injection to rats caused defect of limb and head (Birth Defects (3rd, 2000)) and that the substance produced subfertility and larger doses caused complete sterility in mice (IARC vol. 7 (1974)). It was also reported that intraperitoneal injection to pregnant mice induced high frequencies of midgestation and late fetal deaths, and of malformations among some of the surviving fetuses (HSDB (2008)). The data for oral route are on the document in List 3 and the details are unknown, and other data are results by intraperitoneal injection. Based upon the available information, the substance was classified into Category 2 since there is insufficient evidence to classify it in Category 1B.

This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
