Introduction

Insoluble in water, insoluble in dichloromethane, ether, benzene and acetone.

Application
2,2′-Dithiosalicylic acid (DTBA, DTSA) is a versatile organosulfur intermediate widely used across the pharmaceutical, polymer, and agrochemical industries. As a pharmaceutical intermediate, it serves as a key precursor for the synthesis of thioethers, thioxanthone photoinitiators (ITX), biocides (BIT, Proxel), and disinfectants. It is also an essential certified reference standard (Thimerosal Related Compound A) for quality control and analytical method validation in the production of mercury‑based preservatives. In polymer chemistry, DTBA functions as a robust crosslinking agent and hardener for epoxy resins, enabling the production of recyclable vitrimers, self-healing elastomers, and high‑performance thermosets. As a sulfhydryl‑modifying reagent and chelating agent, it is employed in the development of Cu(II)-selective electrochemical sensors and stripping voltammetry. DTBA also serves as a stabilizer for rubber and plastics, a textile dye intermediate, and an antifungal additive for coatings and adhesives. Xinchem offers high‑purity 2,2′-Dithiosalicylic acid with flexible custom synthesis and contract manufacturing, reliably scaled from R&D to commercial tons.
