Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

203-401-0
EC Name:
4-chloroaniline
Cas Number:
106-47-8
Molecular formula:
C6H6ClN
IUPAC Name:
4-chloroaniline
Details on test material:

Test animals

Species:
rabbit
Strain:
New Zealand White
Sex:
male

Administration / exposure

Type of coverage:
occlusive
Vehicle:
unchanged (no vehicle)
Details on dermal exposure:
-Type of wrap: plastic film
Duration of exposure:
24 h
Doses:
No data on the doses employed were given in the publication. However, the publication stated that doses above 20 ml/kg could not be retained in contact with the skin of the animals

No. of animals per sex per dose:
4
Control animals:
no
Details on study design:
Penetration of rabbit skin was estimated by a technique closely alike to the one-day cuff method of Draize and associates. Before application, the fur was clipped from the entire trunk of the animals and the substance applied under a plastic film for 24h within which time the animals were immobilized (type of wrap: occlusive). The film was removed at the end of the application period and the animals were subsequently caged and observed for another 14d. LD 50 and its fiducial range were estimated by the method of Thompson (Use of Moving averages and interpolation to Estimate Median Effective Dose. Bacteriol. Rev. 1 115 (June 1947) using the tables of Weils (Tables for Convenient Calculation of Median-Effective Dose (LD50 or ED 50) and Instructions in Their Use. Biometrics 8: 249 (Sept. 1952)
