Chemical Structure

H-Ser(Bzl)-OBzl CAS 67321-05-5 chemical structure

Description

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.

H-Ser(Bzl)-OBzl (CAS 67321-05-5) is a high-purity analytical reference standard with the molecular formula C17H19NO3 and a molecular weight of 285.34 g/mol.

Structurally, H-Ser(Bzl)-OBzl (C17H19NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 285.34 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).

As a certified reference material (CRM), H-Ser(Bzl)-OBzl 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.
