Compared with other compounds in its class, the molecular weight of 174.16 g/mol gives 2-(1H-tetrazol-1-yl)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(1H-tetrazol-1-yl)benzaldehyde (CAS 1823366-31-9) is a high-purity analytical reference standard with the molecular formula C8H6N4O and a molecular weight of 174.16 g/mol.
The molecular framework of 2-(1H-tetrazol-1-yl)benzaldehyde (C8H6N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
