Trichloro(diethyl)-λ5-phosphane, also known as trichlorophosphine or phosphorus trichloride, is a chemical compound with the formula PCl3. It is a colorless, volatile, and toxic liquid that is widely used as a reagent in organic synthesis, particularly in the production of organophosphorus compounds. PCl3 is synthesized by reacting phosphorus with chlorine gas, and it is an important intermediate in the preparation of various pesticides, flame retardants, and other industrial chemicals. Due to its high reactivity and potential hazards, it is essential to handle and store PCl3 with proper safety measures to prevent exposure and environmental contamination.

2725-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2725-69-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2725-69:
(6*2)+(5*7)+(4*2)+(3*5)+(2*6)+(1*9)=91
91 % 10 = 1
So 2725-69-1 is a valid CAS Registry Number.
