GALLACE TOPHENONE.-.-GALL OBR OMOL.
This body, originally known as gallacotophenone, is a
derivative of pyrogallol with a formula of CH3CO,CH2-
Physical Properties.-This drug is a yellowish crys-
tallizable powder with a melting-point of 15 8 F. (700 C.).
Solubility.-Gallacetophenone is soluble in hot water,
alcohol, ether, and glycerin.
Therapeutic Applications.-This remedy is chiefly
employed as a substitute for pyrogallol in diseases of
the skin, especially psoriasis.
Administration.-Gallacetophenone is applied locally
in Io per cent. solutions.
This new dermic substance is obtained by heating
gallic acid and anilin and treating the product with
water acidulated with hydrochloric acid.
Physical Properties.-Gallanol occurs in the form of
a white crystalline body having a-slightly bitter taste; it
melts, without decomposition, at 4o0i F. (2050 C.). With
alkalies this drug gives a brown coloration.
Solubility.-This remedy is quite soluble in boiling
water, in alcohol, and in ether, only slightly soluble in
cold water, and insoluble in benzene and chloroform.
Therapeutic Applications.-Gallanol has been used
with alleged advantage in diseases of the skin, particu-
larly in eczema and psoriasis, locally applied.
Administration.-This remedy can be employed in
solution of the strength of Io per cent., or in ointment,
especially with petroleum, in the strength of from io to
25 per cent.
The above name is given to dibromogallic acid, which
is simply gallic acid in which two atoms of hydrogen
have been replaced by two atoms of bromine. The
formula of gallobromol therefore is C6Br2(OH)3CO.OH.
