Chemical Structure
Description
Structurally, ((S)-1-Carboxy-2-(1-(3,5-dichlorobenzyl)-1H-imidazol-5-yl)ethyl)-L-leucine (C19H23Cl2N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 428.31 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).
((S)-1-Carboxy-2-(1-(3,5-dichlorobenzyl)-1H-imidazol-5-yl)ethyl)-L-leucine (CAS 305335-31-3), molecular formula C19H23Cl2N3O4 and molecular weight 428.31 g/mol, is a CATO reference standard with documented purity and traceability.
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.
