5-Phenyl-1H-tetrazol-1-ol CAS 55513-24-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 162.15 g/mol gives 5-Phenyl-1H-tetrazol-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Phenyl-1H-tetrazol-1-ol (CAS 55513-24-1), molecular formula C7H6N4O and molecular weight 162.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Phenyl-1H-tetrazol-1-ol (C7H6N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Phenyl-1H-tetrazol-1-ol 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.
