5-(4-amino-2-oxo-1(2h)-pyrimidinyl)-1,3-oxathiolane-2-carboxylic acid 5-methyl-2-(1-methylethyl)cyclohexyl ester

It is mainly employed to synthesize lamivudine (3TC), an antiviral drug for HIV and hepatitis B. This compound contributes to the formation of the oxathiolane ring in lamivudine and may also serve as a reference standard in quality control during API manufacturing. It is not administered directly to patients and functions only as a key chemical building block in the production of the final antiviral drug. 5-(4-amino-2-oxo-1(2H)-pyrimidinyl)-1,3-oxathiolane-2-carboxylic acid 5-methyl-2-(1-methylethyl)cyclohexyl ester is a pharmaceutical intermediate.
