41444-33-1 Usage

General Description

1-(2-Thienylthio)acetone, also known as tiopronin, is a chemical compound with the molecular formula C6H8OS2. It is a thiol-containing compound with a thione group that is commonly used as a pharmaceutical agent for the treatment of cystinuria and nephrolithiasis. Tiopronin has been shown to be a chelating agent, which means it can bind to heavy metals and help remove them from the body. In addition, it has been studied for its potential antioxidant and anti-inflammatory properties. Tiopronin is also used in the synthesis of various organic compounds and as a reagent in chemical reactions. Overall, 1-(2-Thienylthio)acetone has a wide range of applications in the medical, pharmaceutical, and chemical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 41444-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 41444-33:
91 % 10 = 1
So 41444-33-1 is a valid CAS Registry Number.

Substituted α-Sulfur Methyl Carbanions: Effective Homologating Agents for the Chemoselective Preparation of β-Oxo Thioethers from Weinreb Amides

Senatore, Raffaele,Ielo, Laura,Urban, Ernst,Holzer, Wolfgang,Pace, Vittorio

supporting information, p. 2466 - 2470 (2018/05/03)

The proper generation of α-thiomethyllithium reagents via reductive lithiation or deprotonation followed by reaction with variously functionalized Weinreb amides represents an excellent method to access β-oxo thioethers. The procedure is adaptable to alky


Fernandez, I.,Llera, J. M.,Zorrilla, F.,Alcudia, F.

, p. 291 - 301 (2007/10/02)

The synthesis and conformational analysis of the title compounds are reported.The conformational properties of the 2-thienyl derivatives, deduced from 1H-nmr and ir data, are compared with those for 2-furyl analogs and the results have been interpreted taking into account the stronger (OH...Ring) intramolecular association in the 2-furyl derivatives.
