5954-70-1

3-Butene-1-thiol, also known as 3-butenyl mercaptan, is an organic compound with the chemical formula C4H8S. It is a colorless liquid with a strong, pungent odor, and it is a member of the thiol family, which are characterized by the presence of a sulfur-hydrogen bond (-SH). 3-Butene-1-thiol is an important intermediate in the synthesis of various chemicals, including pharmaceuticals, agrochemicals, and fragrances. It is also used as a flavoring agent in the food industry to impart a sulfurous, onion-like taste. 3-Butene-1-thiol is produced industrially through various methods, such as the reaction of allyl chloride with hydrogen sulfide or the hydrolysis of 3-butenyl disulfide. Due to its strong odor, it is often used as a warning agent in natural gas to detect leaks, as it is added to odorless natural gas to make it easily detectable by smell.

5954-70-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5954-70-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,5 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5954-70:
(6*5)+(5*9)+(4*5)+(3*4)+(2*7)+(1*0)=121
121 % 10 = 1
So 5954-70-1 is a valid CAS Registry Number.

TRANSFORMATIONS OF 2-METHYLTHIACYCLOBUTANE IN THE PRESENCE OF ALUMINUM OXIDE

Yuskovich, A. K.,Danilova, T. A.,Viktorova, E. A.

, p. 141 - 144 (2007/10/02)

The transformations of 2-methylthiacyclobutane at 150-350 deg C in the presence of γ-Al2O3 samples with different aprotic acidities were investigated.It was established that the sulfide undergoes isomerization via two pathways, viz., with ring expansion to a five-membered ring and with opening at one C-S bond to give an unsaturated thiol.An experimental confirmation of the consecutive formation of hydrogen sulfide from a one-ring sulfide through a step involving the formation of an unsaturated thiol was obtained for the first time.The transformations are realized asa result of both ionic and polymerization-depolymerization processes.
