Ueber zwei Dinitromethyl-p-toluidine;

p-Chloro-o-toluidine and its hydrochloride.

There is limited evidence for the carcinogenicity of p‐chloro-o-toluidine from epidemiological studies in humans. Three cohort studies found high relative risks for urinary-bladder cancer among workers exposed to p-chloro-o-toluidine; however, confounding by coexposure to other potential urinary-bladder carcinogens could not be ruled out. Documented human exposure to p‐chloro-o-toluidine has oc...

N-(4-Methyl-2-pyrid­yl)-p-toluidine

In the title compound, C(13)H(14)N(2), the dihedral angle between the aromatic rings is 48.1 (1)° and the bridging C-N-C bond angle is 127.24 (12)°. In the crystal, intermolecular N-H⋯N hydrogen bonding about a center of inversion generates a hydrogen-bonded dimer.

Bioassay of 3-chloro-p-toluidine for possible carcinogenicity.

A bioassay for the possible carcinogenicity of 3-chloro-p-toluidine was conducted using Fischer 344 rats and B6C3F1 mice. 3-Chloro-p-toluidine was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty animals of each sex and species were placed on test as controls. The time-weighted average dietary concentrations of 3-chlor...

irrelevant. Chemistry and the relations between science, technology, and industry are well surveyed by Crosland and Cardwell respectively. Forbes's essay on mathematical cosmography is not a comprehensive account but the story (albeit interesting) of a few German cartographers. Compared with other recent collections of essays in the history of science, this volume parades no party line: witness...
