Background

Tris(2-carboxyethyl) phosphine hydrochloride (TCEP hydrochloride, CAS 51805-45-9) is a water-soluble reducing agent widely employed in biochemical research. As a non-volatile, thiol-free compound, it cleaves disulfide bonds via a selective reduction reaction, converting them into free thiols. TCEP hydrochloride facilitates the reduction of various functional groups, including azides, sulfonyl chlorides, nitroxides, and dimethyl sulfoxide derivatives, thus serving as a versatile reagent in organic synthesis. In biological assays, this reagent allows the complete reduction of dehydroascorbic acid (DHA) to ascorbic acid under acidic conditions within samples. It is commonly used in combination with proteolytic enzymes to support protein digestion and hydrogen-deuterium exchange analyses.
