Chemical Structure

Calcitonin Salmon Impurity 24 CAS 17854-07-8 chemical structure

Description

The molecular framework of Calcitonin Salmon Impurity 24 (C38H30) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

Calcitonin Salmon Impurity 24 (CAS 17854-07-8) is a high-purity analytical reference standard with the molecular formula C38H30 and a molecular weight of 486.64 g/mol.

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.
