Dielectric properties of thiazine derivatives

Electrochimica Acta, 1968
Abstract The thiazine derivatives promethazine, chlorpromazine, trimeprazine, prochlorperazine, trifluoperazine, methotrimeprazine and thioproperazine exhibit similar dielectric behaviour, and all except the last two are subject to severe supercooling.

The Chemical Analysis of Thiazin Eosinates

Stain Technology, 1929
The constituents of blood stains are normal eosinates of the thiazin series of dyes. Methods are outlined for the chemical examinations of blood stains which are based upon the complete reduction of all dye components present in buffered solutions of limited acidity, and the reduction of their thiazin components alone in strongly acid solutions ...

Studies on derivatives of tetrahydro [1,3]-thiazine.

Archivum immunologiae et therapiae experimentalis, 1978
In the course of studies on compounds with expected antiinflammatory and immunosuppressive activity a series of new derivatives of tetrahydro [1,3]-thiazine-4-one-6-carboxylic acid, tetrahydro [1,3]-thiazine-4,6-dione and 2-thiobarbituric acid have been synthetized.

1,2-Thiazines and benzo derivatives

1991
Sulfur atoms can exhibit a valency of four allows the formation of 1-substituted 1, 2-thiazines with a double bond between two heteroatoms, and the second bond elsewhere in the ring. Although these compounds could be described as “dihydro derivatives,” they are isomeric with 1, 2-thiazines, in which the valency of the sulfur atom is two and there is no

1,4-Thiazines and Their Dihydro Derivatives

1979
Publisher Summary This chapter presents the synthesis, reactivity, and physicochemical properties of 1,4-thiazines compounds and their dihydro derivatives. The 1,4-thiazine ring is of importance in nature where, in fusion with the benzene ring, it is found in the trichochrome pigments.
