Description
Cyclopentanethiol is a colorless liquid with a strong, alliaceous odor reminiscent of onion, garlic, horseradish, meat, egg, and burned vegetables. It is known for its unique taste characteristics, which can be detected even at a concentration of 2 ppm. Due to its distinctive flavor profile, Cyclopentanethiol is utilized in various applications across different industries.
Uses
Used in Food Industry:
Cyclopentanethiol is used as a food spice to impart a rich, savory taste to various dishes. Its ability to evoke flavors reminiscent of onion, garlic, and other vegetables makes it a valuable ingredient in enhancing the taste and aroma of food products.
Used in Pharmaceutical Industry:
Cyclopentanethiol serves as a pharmaceutical intermediate, playing a crucial role in the synthesis of various drugs and medications. Its unique chemical properties make it a versatile building block for developing new pharmaceutical compounds.
In terms of environmental impact, the annual production of Cyclopentanethiol is relatively low, at less than 1.00 lb, indicating that its use is highly specialized and controlled. This ensures that the application of Cyclopentanethiol remains focused on its specific functions in the food and pharmaceutical industries, without causing significant environmental concerns.
Preparation
From cyclopentyl bromide and potassium hydrosulfide; by treating cycloalkanone dimethyl dithioacetals with four equivalents
of an alkaline metal; from cyclopentyl naphthyl sulfide and an aluminosilicate catalyst.
Safety Profile
A human poison. A
flammable liquid. When heated to
decomposition it emits toxic vapors of SOx
Check Digit Verification of cas no
The CAS Registry Mumber 1679-07-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1679-07:
(6*1)+(5*6)+(4*7)+(3*9)+(2*0)+(1*7)=98
98 % 10 = 8
So 1679-07-8 is a valid CAS Registry Number.
