Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 545349-40-4 3-Chloro-N-(5-nitropyridin-2-yl)propanamide MFCD03388031.
545349-40-4 3-Chloro-N-(5-nitropyridin-2-yl)propanamide MFCD03388031 (CAS 545349-40-4), molecular formula C8H8ClN3O3 and molecular weight 229.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 545349-40-4 3-Chloro-N-(5-nitropyridin-2-yl)propanamide MFCD03388031 (C8H8ClN3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
