Chemical Structure

[5-D-Tyr]Cetrorelix CAS CATO-C4X-201456 chemical structure

Description

As a certified reference material (CRM), [5-D-Tyr]Cetrorelix 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.

[5-D-Tyr]Cetrorelix (CAS CATO-C4X-201456), molecular formula C70H92ClN17O14 and molecular weight 1431.04 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [5-D-Tyr]Cetrorelix (C70H92ClN17O14) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 33.0, corresponding to approximately 33 ring(s) or double-bond equivalent(s). With a molecular weight of 1431.04 g/mol, it falls into the 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).

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.
