Lavoie, Edmond; Tulley, Lorraine; Fow, Elizabeth; Hoffmann, Dietrich (Naylor Dana Inst. Dis. Prev., Am. Health Found., Valhalla, NY 10595, USA). Mutat. Res., 67(2), 123-31 (English) 1979. CODEN: MUREAV. ISSN: 0027-5107. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The mutagenic activity of several arom. amino and nitro compds. related to 4,4'-methylenedianiline (I, R = R1 = NH2, X = CH2) [101-77-9] towards Salmonella typhimurium tester strains TA100 and TA98 was evaluated. The heteroarom. analogs of I (R = NH2, NO2; R1 = R or H; X = S, O, CH2, or SS) were assayed in rat liver homogenate. The relative mutagenic response was in the order -S- > -O- > -CH2- > -SS-. In both tester strains, 4-aminophenyl sulfone [80-08-0], was inactive with and without microsomal activation. The p-nitrophenyl ethers, sulfides, and disulfides were relatively strong, mutagens without microsomal activation towards TA100. While 4-nitrophenyl disulfide [100-32-3] possed different mutagenic activity than 4-nitrothiophenol [1849-36-1] in TA98, 4-aminophenyl disulfide [722-27-0] had similar mutagenic properties. to 4-aminothiophenol [1193-02-8] in both tester strains TA100 and TA98.

Hypergolic burning of formylidene and furfurylidene amines with red furming nitric acid as oxidizer

Panda, S. P.; Kulkarni, S. G. (Inst. Armament Technol., Poona, India). Def. Sci. J., 27(2), 77-80 (English) 1977. CODEN: DSJOAA.Some chemicals with cas registry numbers like 62-53-3 are also used. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) Section cross-reference(s): 25, 27 N-formylidene and N-furfurylidene derivs. of aniline [62-53-3], p-toluidine [106-49-0], p-anisidine [104-94-9], benzidine [92-87-5], p,p'-methylenedianiline [101-77-9], and p-phenylenediamine [106-50-3] were synthesized and their ignition delay with red fuming nitric acid was measured by a cup test method using a high speed camera. A structure-hypergolicity correlation revealed that a p-Me group inhibits hypergolicity whereas a p-methoxy group accelerates it. Similarly, oxidazable nonconjugated benzene rings increase hypergolicity whereas conjugated benzene rings decrease it. Compacted N-formylidene-p-anisidine [32328-80-6] was found to be hypergolic with an ignition delay of <100 ms. 62-53-3 which is the cas registry number of some chemical is mentioned. ..
