2-Chloro-1,3,2-dioxaphospholane (CAS 822-39-9) is a compound prized for its reactivity, making it an indispensable tool in various chemical syntheses. However, this very reactivity necessitates a thorough understanding of its chemical properties and meticulous handling procedures to ensure safety and product integrity.

At its core, 2-Chloro-1,3,2-dioxaphospholane is a cyclic organophosphorus compound. Its structure features a five-membered ring containing two oxygen atoms and one phosphorus atom, with a chlorine atom bonded to the phosphorus. This chlorine atom is highly susceptible to nucleophilic substitution, making the compound an effective phosphitylating agent. This characteristic is precisely what makes it valuable for introducing phosphorus groups into other molecules, a critical step in the synthesis of pharmaceuticals, agrochemicals, and advanced materials.

A significant property to note is its extreme moisture sensitivity. In the presence of water, 2-Chloro-1,3,2-dioxaphospholane readily hydrolyzes, leading to the formation of phosphoric acid derivatives and releasing hydrochloric acid. This reaction can be vigorous and is why the compound must be stored under strictly anhydrous conditions, ideally under an inert atmosphere such as nitrogen. For any manufacturer or end-user, maintaining a dry environment during storage and handling is non-negotiable. When you buy this product, ensure your supplier provides it in appropriate, tightly sealed packaging.

The physical properties include a low melting point (around -28°C) and a boiling point of approximately 62°C at 20 mmHg, indicating it is a liquid under typical laboratory and industrial conditions. Its appearance is generally described as a clear, colorless to light yellow liquid. Due to its corrosive nature and potential to cause skin and eye irritation, appropriate personal protective equipment (PPE) – including gloves, safety goggles, and lab coats – is essential when handling. Working in a well-ventilated area or a chemical fume hood is also highly recommended.

For businesses seeking to procure this essential chemical, understanding these properties is part of ensuring a successful integration into your processes.
