Light-stable reducible compounds and analytical compositions, elements and methods utilizing same.

摘要

Certain reducible aromatic and quinone compounds having bulky groups on the carbamate nitrogen atom have improved stability to light. These compounds are useful in analytical compositions, elements and methods, for example for assays of bacterial cells. These compounds have suitable substituents that promote the release of phenalenone or benzphenalenone fluorescent dyes at physiological pH.
