Chemical Structure

[1-2Nal]Cetrorelix CAS CATO-C4X-201454 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [1-2Nal]Cetrorelix.

[1-2Nal]Cetrorelix (CAS CATO-C4X-201454) is a high-purity analytical reference standard with the molecular formula C70H92ClN17O14 and a molecular weight of 1431.04 g/mol.

Structurally, [1-2Nal]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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
