Chemical Structure

H-Asp-Leu-OH CAS 3062-14-4 chemical structure

Description

H-Asp-Leu-OH (CAS 3062-14-4), molecular formula C10H18N2O5 and molecular weight 246.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, H-Asp-Leu-OH (C10H18N2O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 246.26 g/mol, it falls into the medium-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.

As a certified reference material (CRM), H-Asp-Leu-OH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
