Polypeptide propoxyphene derivatives for immunoassay reagents

Polypeptide propoxyphene derivatives for immunoassay reagents. Leute, Richard K. (Syva Co., USA). U.S. US 4025501 24 May 1977, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07G007-00. NCL: 260121000. APPLICATION: US 75-560079 20 Mar 1975.There are some reagents like 63692-74-0 is used in this study. DOCUMENT TYPE: Patent CA Section: 1 (Pharmacodynamics) Section cross-reference(s): 4 1,2-Diphenyl-3-methyl-4-dimethylamino-2-butanol-HCl [2214-28-0] was conjugated with methyl succinate monochloride [1490-25-1] to form the acid ester, 4-dimethylamino-1,2-diphenyl-3-methyl-2-butyl methyl succinate [63692-73-9]. The acid group of this compd. was activated several ways and conjugated with proteins (serum albumin and lysosome) in order to make antibodies useful for the detection of propoxyphene [469-62-5] and its N-desmethyl metabolite [32501-12-5]. The method was used to detect propoxyphene and its N-desmethyl metabolite in urine. .

Soap-based detergent formulations: XIX. Amphoteric alkylsuccinamide derivatives as lime soap dispersants.Several substances are used for example 62417-40-7 and 62417-31-6 which are their cas registry numbers. Micich, T. J.; Linfield, W. M.; Weil, J. K. (ERRC, ARS, Philadelphia, Pa., USA). J. Am. Oil Chem. Soc., 54(3), 91-4 (English) 1977. CODEN: JAOCA7. DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 23 The reaction of an alkylamine with MeO2CCH2CH2COCl [1490-25-1], followed by reaction with Me2N(CH2)xNH2 (x = 2 or 3) and propane sultone [1120-71-4], gave RNHCOCH2CH2CONH(CH2)nN+Me2(CH2)3SO3- (n = 2 or 3, R = C8-18 alkyl) which were hygroscopic cryst. solids with good lime soap dispersing ability, water soly., Ca2+ stability, and detergency (alone and with soap or soap-silicate compns.). .
