Ethyl Isothiocyanate (EITC), identified by CAS number 542-85-8, is a chemical compound that possesses a distinct set of physical and chemical properties making it a valuable asset in various industrial synthesis processes. As a colorless liquid, its primary characteristic is its high purity, often specified at ≥99.0%, which is crucial for its applications as an organic synthesis intermediate.

The physical attributes of Ethyl Isothiocyanate include a boiling point of approximately 131.3 °C at 760 mmHg and a melting point of -6 °C, indicating it remains a liquid under typical laboratory and industrial conditions. Its density is around 0.9 g/cm³, and it has a flash point of 32.2 °C, which necessitates careful handling and storage. From a chemical standpoint, the isothiocyanate functional group (-N=C=S) is highly reactive. This allows EITC to readily undergo addition reactions with nucleophiles such as amines, alcohols, and thiols, forming thioureas, thiocarbamates, and dithiocarbamates, respectively. These resultant compounds are foundational in the creation of more complex molecules.

The versatility of Ethyl Isothiocyanate stems directly from this reactivity. In the pharmaceutical industry, it's employed as a key intermediate for synthesizing a wide range of therapeutic agents. Its ability to form nitrogen and sulfur-containing heterocyclic rings is instrumental in developing novel drug candidates. Procurement managers looking to buy ethyl isothiocyanate price effectively for these applications will focus on suppliers that can guarantee high assay percentages, ensuring the integrity of subsequent synthesis steps.

Furthermore, the agrochemical sector relies on EITC for producing effective pesticides and herbicides. The synthesis of thiourea derivatives, for example, can lead to compounds with potent biological activity against pests and weeds. For those intending to purchase ethyl isothiocyanate for agrochemicals, partnering with a reliable manufacturer in China often provides a strategic advantage in terms of both cost and access to technical expertise. When considering cas 542-85-8 organic synthesis, understanding these fundamental properties allows chemists and procurement specialists to make informed decisions about sourcing and application, ensuring optimal results from their supplier of isothiocyanatoethane.
