Nitrogen-containing aromatic heterocyclic (poly)peroxycarboxylic acids having the formula:
wherein R represents a hydrogen atom or a straight or branched alkyl, (hetero)cycloalkyl, (hetero)aryl, alkylaryl or arylalkyl group, wherein said groups are optionally substituted, or a carboxylic group or any other substituents non-reactive in the presence of the active oxygen of the peroxycarboxylic group;
n is a number selected from 0 and 1;
m is a number selected from 1, 2 and 3, and
X represents an acidic anion selected from HSO₄⁻ and CH₃SO₃⁻ , and wherein the pyridinic ring may in its turn be condensed with at least one further (hetero) aromatic or (hetero)cycloalkylic ring.
Also described is their preparation process and their use as bleaching agents.

其中 R 代表氢原子或直链或支链烷基、(杂)环烷基、(杂)芳基、烷芳基或芳烷基,其中所述基团任选被取代,或羧基或在过氧羧基的活性氧存在下不反应的任何其他取代基;
n 是选自 0 和 1 的数字;
m 是选自 1、2 和 3 的数字,以及
X 代表选自 HSO₄- 和 CH₃SO₃- 的酸性阴离子,其中吡啶环可依次与至少另一个(杂)芳香环或(杂)环烷基环缩合。
