HISTORY: The SIDS Dossier and Testing Plan were reviewed at the 3rd SIDS Review Meeting where the following SIDS Testing Plan was agreed: no testing () testing (x) Testing on developmental toxicity/teratogenicity was underway at the time of the review meeting. The SIDS Initial Assessment Report was discusse d at SIAM 6 in 1997. It was recommended that the report should be re-drafted and present...
متن کاملBioassay of N-phenyl-p-phenylenediamine for possible carcinogenicity.
A bioassay of N-phenyl-p-phenylenediamine for possible carcinogenicity was conducted by administering the test chemical in the diet to Fischer 344 rats and B6C3F1 mice. Groups of 50 rats of each sex were administered N-phenyl-p-phenylenediamine at one of two doses, either 600 or 1,200 ppm, for 78 weeks and were then observed for 26 additional weeks. Matched controls consisted of groups of 20 un...
متن کاملDetermination of ammonia based on the electrochemical oxidation of N,N'-diphenyl-1,4-phenylenediamine in propylene carbonate.
The oxidation of N,N'-diphenyl-1,4-phenylenediamine (DPPD) has been studied by cyclic voltammetry at glassy carbon electrodes in propylene carbonate. Next, the reaction between ammonia and DPPD was similarly investigated. It has been shown that ammonia reversibly removes protons from oxidized DPPD molecules, thus facilitating the oxidative process with the emergence of a new wave at less positi...
متن کاملP,P-Diphenyl-N-(1,1,2,2-tetraphenyl-1λ5-diphosphanylidene)phosphinous amide
The title compound, C(36)H(30)NP(3), a structural isomer of tris-(diphenyl-phosphino)amine, was unexpectedly isolated as the sole phospho-rus-containing product from the reaction of Mg[N(PPh(2))(2)](2)(THF)(2) (THF is tetra-hydro-furan) with CO(2). Its identity was confirmed by (31)P NMR spectroscopy and single-crystal X-ray diffraction. The geometry at the two P(III) atoms is trigonal pyramida...
متن کامل1,1′-(Diselanediylbis{[P,P-diphenyl-N-(trimethylsilyl)phosphorimidoyl]methanylylidene})bis[1,1-diphenyl-N-(trimethylsilyl)-λ5-phosphanamine] pentane disolvate
The title compound, C62H78N4P4Se2Si4·2C5H12, is made up of two [SeC(PPh2NSiMe3)(PPh2NHSiMe3)] units related by an inversion center situated at the mid-point of the diselenide bond. It crystallized with two disordered mol-ecules of pentane used as solvent of crystallization. It is a rare example of an anti-periplanar diselenide and exhibits a long Se-Se bond of 2.4717 (8) Å. The Se-C bond length...
