Ibuprofen Impurity 5 CAS 100319-40-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.27 g/mol gives Ibuprofen Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ibuprofen Impurity 5 (CAS 100319-40-2) is a high-purity analytical reference standard with the molecular formula C12H18 and a molecular weight of 162.27 g/mol.

Ibuprofen Impurity 5 (C12H18) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
