What Is Salcaprozate sodium?
Salcaprozate sodium (CAS 203787-91-1), commonly abbreviated SNAC, is the monosodium salt of 8-[(2-hydroxybenzoyl)amino]octanoic acid. Molecular formula C15H20NNaO4; molecular weight about 301.31 g/mol. Always match CAS 203787-91-1 on the batch COA.
Supplier and formulation literature describe SNAC as an oral absorption promoter / chemical permeation enhancer used to support gastrointestinal delivery of poorly permeable actives, including selected peptides, proteins and other macromolecules in research and development formulations. Monuo Chemical supplies Salcaprozate sodium as a specialty chemical raw material under Custom synthesis, with batch identity documentation (COA / SDS). Finished-product claims, labeling and local regulatory filings remain the brand manufacturer’s responsibility. Confirm grade and assay against the batch COA for your intended method.
