Description

CAS: 26555-40-8 | C2H3ClO2S | 126.554 g/mol

Methoxycarbonylsulfenyl chloride is used to prepare 3-[(methoxycarbonyl)dithio]-L-alanine by reacting with L-cysteine. Further, it is used in the synthesis of 3-2 pyridinyldithio propanoic acid hydrazide (PDPH). It serves as an important heterobifunctional crosslinker, which is a crosslinker used to make macromolecule-drug conjugates.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
