2-chloro-N-[2-fluoro-5-(1H-1,2,3,4-tetrazol-1-yl)phenyl]acetamide CAS 1184236-16-5 chemical structure

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-chloro-N-[2-fluoro-5-(1H-1,2,3,4-tetrazol-1-yl)phenyl]acetamide (CAS 1184236-16-5) is a high-purity analytical reference standard with the molecular formula C9H7ClFN5O and a molecular weight of 255.64 g/mol.

Structurally, 2-chloro-N-[2-fluoro-5-(1H-1,2,3,4-tetrazol-1-yl)phenyl]acetamide (C9H7ClFN5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 255.64 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
