Chemical Structure
Description
The occurrence of (S)-2-Amino-5-(carbamimidoyloxy)pentanoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-2-Amino-5-(carbamimidoyloxy)pentanoic acid (CAS 40736-35-4), a certified reference material (molecular formula C20H28O5, MW 348.43 g/mol) for analytical method development and quality control.
Structurally, (S)-2-Amino-5-(carbamimidoyloxy)pentanoic acid (C20H28O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 348.43 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
