2,4-Dichloro-N-[(5-methyl-1H-1,3-benzodiazol-2-yl)methyl]benzamide CAS 338410-52-9

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.

2,4-Dichloro-N-[(5-methyl-1H-1,3-benzodiazol-2-yl)methyl]benzamide (CAS 338410-52-9), molecular formula C16H13Cl2N3O and molecular weight 334.20 g/mol, is a CATO reference standard with documented purity and traceability.

2,4-Dichloro-N-[(5-methyl-1H-1,3-benzodiazol-2-yl)methyl]benzamide (C16H13Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
