Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.15 g/mol gives Xanomeline impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Xanomeline impurity 36 (CAS 98276-73-4) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8N2O2 and a molecular weight of 152.15 g/mol.
The molecular framework of Xanomeline impurity 36 (C7H8N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
