2-(5-Imino-2,5-dihydro-1h-tetrazol-1-yl)acetic acid CAS 21743-62-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 143.10 g/mol gives 2-(5-Imino-2,5-dihydro-1h-tetrazol-1-yl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(5-Imino-2,5-dihydro-1h-tetrazol-1-yl)acetic acid (CAS 21743-62-4), a certified reference material (molecular formula C3H5N5O2, MW 143.10 g/mol) for analytical method development and quality control.

The molecular framework of 2-(5-Imino-2,5-dihydro-1h-tetrazol-1-yl)acetic acid (C3H5N5O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 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).

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), 2-(5-Imino-2,5-dihydro-1h-tetrazol-1-yl)acetic 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.
