2,2'-[丙烷-2,2-二基双(硫代)]二乙酸 (CAS No.4265-58-1)

Product Name:2,2'-[Propane-2,2-diylbis(thio)]diacetic acid

English Name:2,2'-[Propane-2,2-diylbis(thio)]diacetic acid

CAS No.:4265-58-1

Aliases:TK-COOH, 2,2'-[(1-Methylethylidene)bis(thio)]diacetic acid

Molecular Formula:C7H12O4S2

Physical Properties:White to off-white powder, freely soluble in common aqueous solutions and most organic solvents (e.g. water, DMSO, ethanol). Stable for at least 12 months when stored dry and protected from light at -20°C; avoid repeated freeze-thaw cycles. Store below 4°C in a dry, dark environment; handling under inert gas is recommended for optimal stability.

Uses:This compound is a reactive oxygen species (ROS)-responsive thioketal linker, commonly used in the synthesis of ROS-responsive drug delivery systems, nanocarriers, and smart hydrogels. It is also employed in preparing biodegradable materials under oxidative stress conditions, as well as in bioconjugation and surface modification for pharmaceutical and chemical research.
