Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-(1H-tetrazol-1-yl)phenyl)-2-chloroacetamide.
N-(4-(1H-tetrazol-1-yl)phenyl)-2-chloroacetamide (CAS 355826-97-0) is a high-purity analytical reference standard with the molecular formula C9H8ClN5O and a molecular weight of 237.65 g/mol.
N-(4-(1H-tetrazol-1-yl)phenyl)-2-chloroacetamide (C9H8ClN5O) 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
