4700-45-2

Selenocyanic acid, butyl ester, also known as butyl selenocyanoformate, is an organoselenium compound with the chemical formula C5H9OSe. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. Selenocyanic acid, butyl ester is synthesized by the reaction of butyl alcohol with selenocyanic acid, which is derived from the reaction of selenium and hydrogen cyanide. Selenocyanic acid, butyl ester, is primarily used as a reagent in organic synthesis, particularly in the preparation of various selenides and as a protecting group in peptide synthesis. Due to its reactivity and potential toxicity, it should be handled with care and used in well-ventilated areas.

4700-45-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4700-45-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4700-45:
(6*4)+(5*7)+(4*0)+(3*0)+(2*4)+(1*5)=72
72 % 10 = 2
So 4700-45-2 is a valid CAS Registry Number.

Ion-pair extraction of thiocyanate from plasma and its gas chromatographic determination using on-column alkylation

Jacob III,Savanapridi,Yu,et al.

, p. 1692 - 1695 (1984)

Tributylsulfonium thiocyanate may be extracted from aqueous solutions with organic solvents. Injection into the heated injection port of a gas chromatograph results in conversion to the volatile derivative butyl thiocyanate. Tributylsulfonium selenocyanate undergoes analogous extraction and thermal conversion to the butyl derivative. A procedure has been developed for the extraction of thiocyanate from human plasma and gas chromatographic determination using selenocyanate as an internal standard. The method has good sensitivity and precision and has been applied to behavioral and pharmacologic studies of smokers.
