Chemical Structure

Tinidazole Impurity 19 CAS 872301-12-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 134.24 g/mol gives Tinidazole Impurity 19 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tinidazole Impurity 19 (CAS 872301-12-7) is a certified pharmaceutical impurity reference standard with the molecular formula C6H14OS and a molecular weight of 134.24 g/mol.

Based on its molecular formula C6H14OS, Tinidazole Impurity 19 contains sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 134.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
