At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the efficacy of agricultural products often hinges on the quality and precise characteristics of their precursor chemicals. Tris(2-chloroethyl) Phosphite (CAS 140-08-9) is one such compound, vital for the synthesis of plant growth regulators like Ethephon. Delving into its specific properties is key to appreciating its role in chemical manufacturing processes and its impact on crop science.

Tris(2-chloroethyl) Phosphite is most commonly described as a colorless oily liquid. This physical state is advantageous for industrial handling and processing, allowing for smooth integration into liquid-based chemical reactions. Its specific gravity is noted as 1.328 g/mL at 25 °C, indicating it is denser than water. The boiling point range of 112-115 °C at 2 mm Hg suggests a relatively low volatility under atmospheric pressure, which is beneficial for process control and minimizing loss during handling or reaction.

The refractive index, n20/D 1.487, is another critical physical parameter that aids in identifying and verifying the purity of the compound. For users involved in the chemical synthesis of ethephon, these precise measurements are essential for ensuring reaction stoichiometry and product yield. The flash point of 375 °F points to its flammability characteristics, requiring appropriate safety precautions during storage and use in industrial settings.

Storage recommendations for Tris(2-chloroethyl) Phosphite emphasize a cool, ventilated place. This is standard practice for many organic chemicals to prevent degradation caused by heat or moisture, and to mitigate any potential fire hazards. Maintaining the compound's integrity is paramount, as impurities or degradation can significantly affect the downstream synthesis of Ethephon, potentially leading to reduced efficacy or unforeseen by-products in the final agricultural product.

The vapor pressure is reported as 0.00359 mmHg at 25°C, which is quite low, further indicating its low volatility. This is a safety advantage as it reduces the risk of inhalation exposure. The molecular formula C6H12Cl3O3P and molecular weight of 269.49000 provide the fundamental chemical identity, essential for stoichiometric calculations in synthesis.

As a key component in the production of plant growth regulators, Tris(2-chloroethyl) Phosphite supports advancements in specialty agrochemicals. Its consistent availability and well-defined characteristics are foundational for the agricultural industry's ability to innovate and meet the growing global demand for food. Companies sourcing this intermediate can be confident in its suitability for demanding applications when handled according to established safety and storage protocols.
