Product Name:3-(2-Pyridyldithio)propanoic acid
English Name:3-(2-Pyridyldithio)propanoic acid
CAS No.:68617-64-1
Aliases:3-(Pyridin-2-yldisulfanyl)propanoic acid, 2-Pyridyldithiopropanoic acid, PDP acid
Molecular Formula:C8H9NO2S2
Physical Properties:White to off-white crystalline powder; molecular weight 215.29; melting range approximately 110–118 °C (literature); soluble in methanol, ethanol, DMSO and other organic solvents, slightly soluble in water; aqueous solution is weakly acidic; sensitive to light, heat and moisture, recommended to be stored sealed at low temperature, protected from light.
Uses:This product is a thiol-reactive reagent containing a pyridyldithio group. It reacts with thiol groups in proteins, peptides or nucleic acids via disulfide exchange to achieve site-specific conjugation. As a key precursor of the heterobifunctional crosslinker SPDP, it is widely used in the preparation of antibody-drug conjugates (ADCs), enzyme labels and biosensors, as well as in solid-phase synthesis to introduce reducible disulfide linkers.
