Phosphoro(thiocyanatidic)acid, diethyl ester, also known as O,O-diethyl phosphorodithiocyanate, is an organophosphorus compound with the chemical formula C5H10NPS2. It is a colorless to pale yellow liquid with a pungent odor. Phosphoro(thiocyanatidic)acid, diethyl ester (8CI,9CI) is primarily used as a pesticide, specifically as an acaricide, to control mites and ticks in agriculture. It works by inhibiting the acetylcholinesterase enzyme in the nervous system of the target pests, leading to their paralysis and death. Due to its potential toxicity and environmental concerns, its use has been restricted or banned in some countries. It is important to handle this chemical with care, following proper safety procedures to minimize risks to human health and the environment.

3220-87-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3220-87-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3220-87:
(6*3)+(5*2)+(4*2)+(3*0)+(2*8)+(1*7)=59
59 % 10 = 9
So 3220-87-9 is a valid CAS Registry Number.

THIOCYANATION OF DIALKYL PHOSPHITES AND THEIR STRUCTURAL ANALOGUES BY THIOCYANOGEN (SCN)2: MECHANISM AND STEREOCHEMISTRY

Lopusinski, A.,Luczak, L.,Michalski, J.

, p. 679 - 683 (1982)

The thiocyanation of organophosphorus compounds containing >P(X)H functional groups (X=O,S) has been reinvestigated.The reaction was shown to be highly stereospecific and proceeds with the retention of configuration at P via the thiocyanidate >P(O)SCN structure.The thiocyanidates rearrange into the isothiocyanidates >P(O)NCS with a rate depending on structure of substrates and reaction conditions.The thiocyanation reaction of dialkyl phosphite and their structural analogues offers an excellent route to the isothiocyanidates >P(X)NCS and in some cases also the thiocyanidates >P(X)SCN.
