1,6-Hexanedithiol, identified by its CAS number 1191-43-1, is a fascinating organic compound that plays a pivotal role in various scientific and industrial domains. Characterized by its two terminal thiol (-SH) groups, this dithiol molecule offers unique reactivity that is leveraged in advanced material science, chemical synthesis, and even the food industry. Understanding its chemical properties is the first step to appreciating its extensive applications.

The molecule's structure, a six-carbon alkane chain with thiol groups at each end, gives it a bifunctional character. This allows it to act as a crosslinker or a surface modifier. Its density is approximately 0.983 g/cm³, with a boiling point between 118-119°C at 15 mmHg, and a melting point of -21°C. These physical attributes, combined with a flash point of 195°F, indicate a compound that is stable under typical industrial conditions but requires careful handling. The refractive index of 1.511 further describes its optical properties.

The reactivity of the thiol groups is central to its utility. 1,6-Hexanedithiol readily forms strong covalent bonds with metal surfaces, making it ideal for creating self-assembled monolayers (SAMs). These SAMs are crucial in applications such as anchoring surface atoms on substrates like gold nanoparticles, which is vital for bioanalytical tools and sensors. This application in material science highlights the compound's importance in cutting-edge technological advancements.

Furthermore, 1,6-Hexanedithiol is a valuable reagent in organic synthesis. It serves as a precursor for various chemicals, including pharmaceuticals and specialty polymers. Its role in polymer chemistry extends to functionalizing materials like molybdenum disulfide (MoS2), thereby enhancing their performance in electronic and optoelectronic devices. The demand for high-purity 1,6-Hexanedithiol for these applications drives the need for reliable manufacturers and suppliers, with China being a significant production hub.

The compound’s versatility is further demonstrated by its use in the food industry as a flavor enhancer. It can impart subtle meaty or burnt notes to spices. However, its application in food is strictly regulated, with usage levels kept below 1 ppm due to its potent odor and potential for off-flavors if misused. Proper storage and handling are crucial; it should be kept in cool, well-ventilated areas to maintain its integrity and prevent degradation. Sourcing from experienced suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to product specification data and adherence to quality standards for both industrial and specialized applications.
