Chemical Structure
Description
The occurrence of Fmoc-S-3-amino-5-hexynic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Fmoc-S-3-amino-5-hexynic acid (CAS 1217669-02-7), molecular formula C21H19NO4 and molecular weight 349.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Fmoc-S-3-amino-5-hexynic acid (C21H19NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 349.38 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
