Please rest assured to buy ademetionine butanedisulfonate in stock here and get quotation from our factory. Customized orders are welcome.
Ademetionine 1,4-Butanedisulfonate (CAS 101020-79-5) is a physiologically active molecule widely found in human tissues and body fluids. As a methyl donor (transmethylation) and precursor of physiological sulfhydryl compounds (transsulfuration), it participates in key biochemical reactions in vivo.
This product regulates liver cell membrane fluidity via phospholipid methylation and promotes the synthesis of sulfur-containing metabolites during detoxification, effectively preventing intrahepatic cholestasis. It is indicated for intrahepatic cholestasis in pre-cirrhotic and cirrhotic conditions, as well as cholestasis of pregnancy.

Ademetionine 1,4-Butanedisulfonate (CAS 101020-79-5) is a high-purity API for liver disease treatment and a key raw material in intrahepatic cholestasis therapy. Its mechanism restores hepatocyte membrane fluidity and enhances sulfur compound synthesis, laying a solid material foundation for treating cholestasis in pre-cirrhotic, cirrhotic and pregnancy conditions. As reputable China Ademetionine 1,4-Butanedisulfonate manufacturers, we ensure stable supply of high-grade raw material.
Product Features

Ademetionine 1,4-Butanedisulfonate is a high-purity liver disease API that acts precisely on hepatocytes, regulating membrane fluidity through transmethylation with minimal interference to normal physiological pathways, showing high specificity and strong targeting.
This raw material significantly improves intrahepatic cholestasis and promotes sulfur-containing metabolite synthesis during detoxification, providing core pharmacological support for intervention in cirrhosis-related and pregnancy-related cholestasis.
With a clear and definite mechanism, it performs stably in improving liver function and reducing bilirubin levels, offering reliable raw material support for chronic liver disease drug development.
It features excellent formulation compatibility and stable pharmacological activity, suitable for injections, enteric-coated tablets and other dosage forms, making it an ideal raw material for preclinical research and innovative liver drug development.
As a classic liver disease API, it excels in promoting bile excretion and protecting hepatocyte function, providing vital support for intrahepatic cholestasis treatment.
