2-Methyl-4-pyrrolidinomethyl benzophenone CAS 898775-91-2

Description

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.

2-Methyl-4-pyrrolidinomethyl benzophenone (CAS 898775-91-2), molecular formula C19H21NO and molecular weight 279.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H21NO, 2-Methyl-4-pyrrolidinomethyl benzophenone contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 279.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
