5-Nitro-2-[(1-phenyl-1h-1,2,3,4-tetrazol-5-yl)sulfanyl]benzoic acid CAS 309726-59-8

Description

5-Nitro-2-[(1-phenyl-1h-1,2,3,4-tetrazol-5-yl)sulfanyl]benzoic acid (C14H9N5O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

5-Nitro-2-[(1-phenyl-1h-1,2,3,4-tetrazol-5-yl)sulfanyl]benzoic acid (CAS 309726-59-8), molecular formula C14H9N5O4S and molecular weight 343.32 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 5-Nitro-2-[(1-phenyl-1h-1,2,3,4-tetrazol-5-yl)sulfanyl]benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
