1-(2,4-Dichloro-5-methoxyphenyl)-5-(4-nitrophenyl)-1H-tetrazole CAS 338961-26-5 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.

CATO supplies 1-(2,4-Dichloro-5-methoxyphenyl)-5-(4-nitrophenyl)-1H-tetrazole (CAS 338961-26-5), a certified reference material (molecular formula C14H9Cl2N5O3, MW 366.16 g/mol) for analytical method development and quality control.

Structurally, 1-(2,4-Dichloro-5-methoxyphenyl)-5-(4-nitrophenyl)-1H-tetrazole (C14H9Cl2N5O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 366.16 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
