About Rhodanine, 97%

Vaqora Chemicals supplies Rhodanine, a sulfur heterocycle registered under CAS number 141-84-4 with a typical assay of 97%. Formula C3H3NOS2, molecular weight 133.2 g/mol. Its systematic (IUPAC) name is 2-sulfanylidene-1,3-thiazolidin-4-one. Common synonyms include 2-Thioxo-4-thiazolidinone and 2-thioxothiazolidin-4-one.

The material typically appears as light yellow to dark yellow to dark beige powder or crystals. Key physical data: a melting point of 165-169 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Typical applications include organic synthesis and API synthesis. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Rhodanine in 25 g, 100 g, 1 kg and 25 kg packs with a batch-specific COA, and ship to customers worldwide.
