Chemical Structure

Z-Leu-Ser-OMe CAS 40290-56-0 chemical structure

Description

As a certified reference material (CRM), Z-Leu-Ser-OMe 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.

Z-Leu-Ser-OMe (CAS 40290-56-0), molecular formula C18H26N2O6 and molecular weight 366.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Z-Leu-Ser-OMe (C18H26N2O6) contains a flavonoid core, an amide group, 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 366.41 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
