Metformin Impurity 27 CAS 18240-93-2 chemical structure

Description

CATO supplies Metformin Impurity 27 (CAS 18240-93-2), a certified reference material (molecular formula C5H13N3, MW 115.18 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H13N3, Metformin Impurity 27 contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 115.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
