538-71-6 Usage
Description
Domiphen is a quaternary ammonium compound and cationic surfactant with antimicrobial activity. It is active against A. viscosus, A. naeslundii, S. mutans, E. coli, and L. monocytogenes bacteria and inhibits C. neoformans yeast growth and spore germination. It also inhibits the human-ether-a-go-go-related gene (hERG) channel (IC50 = 1.5 μM in a whole-cell patch-clamp assay). Formulations containing domiphen have been used as antiseptics, disinfectants, and biocides in industrial, agricultural, veterinary, and clinical applications.
Originator
Bradosol,Ciba,US,1958
Uses
Domiphen bromide is employed as a phase transfer catalyst in synthetic chemistry. It is used as a quaternary ammonium cation with cationic surfactant properties. Further, it is used as an antiseptic and an active pharmaceutical ingredient.
Manufacturing Process
7 parts of β-phenoxyethyl-dimethylamine are heated for 2 hours on the boiling
water-bath with 11 parts of dodecyl bromide. A good yield of β-phenoxy-ethyldimethyl-dodecyl-ammonium bromide is obtained which, after recrystallization
from acetone, melts at 112°C. It is a white crystalline powder which dissolves
easily in water to give a neutral reaction.
Safety Profile
Poison by intraperitoneal
and intravenous routes. hfutauon data reported.
When heated to decomposiuon it emits very toxic
fumes of NOx, NH3, and Br-. See also
BROMIDES.
Check Digit Verification of cas no
The CAS Registry Mumber 538-71-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 538-71:
(5*5)+(4*3)+(3*8)+(2*7)+(1*1)=76
76 % 10 = 6
So 538-71-6 is a valid CAS Registry Number.

-
, (2008/06/13)
Dentifrice containing, in combination, (A) a poly(hydroxypropyl ether) nonionic surfactant, and (B) a cationic polymer selected from the group consisting of (i) a vinylpyrrolidone/dialkylaminoalkyl or -hydroxyalkyl acrylate or methacrylate, quaternized or nonquaternized and (ii) a cationic polysaccharide. This dentifrice is characterized by good foamability, pleasant taste and it does not attack the buccal mucosae and the gums.
