Chemical Structure

Posaconazole Impurity 149 CAS 27871-49-4 chemical structure

Description

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.

Posaconazole Impurity 149 (CAS 27871-49-4) is a certified pharmaceutical impurity reference standard with the molecular formula C4H8O3 and a molecular weight of 104.10 g/mol.

Based on its molecular formula C4H8O3, Posaconazole Impurity 149 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 104.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
