2-Aminothiophenol is an aromatic compound featuring an amino group (-NH2) and a thiol (-SH) substituent on a benzene ring, widely used as a precursor in pharmaceutical synthesis, agrochemicals, and organic electronics. It serves as a key intermediate for dyes, corrosion inhibitors, and sulfur-containing heterocycles. This chemical has a CAS number of 137-07-5, a molecular formula of H2NC6H4SH, and a molecular weight of 125.18 g/mol. It is typically stored at ambient conditions but requires careful handling due to its "Danger" classification for toxicity and corrosivity. Molekula supplies 2-Aminothiophenol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
