Methazolamide Impurity 6 CAS CATO-C4X-34046

Description

Compared with other compounds in its class, the molecular weight of 241.76 g/mol gives Methazolamide Impurity 6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methazolamide Impurity 6 (CAS CATO-C4X-34046) is a certified pharmaceutical impurity reference standard with the molecular formula C13H19NOHCl and a molecular weight of 241.76 g/mol.

Structurally, Methazolamide Impurity 6 (C13H19NOHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 241.76 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
