Chemical Structure
Description
Phenyl(1h-1,2,3,4-tetrazol-5-yl)methanamine hydrochloride (CAS 437768-48-4), molecular formula C8H9N5HCl and molecular weight 211.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Phenyl(1h-1,2,3,4-tetrazol-5-yl)methanamine hydrochloride (C8H9N5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 211.65 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).
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), Phenyl(1h-1,2,3,4-tetrazol-5-yl)methanamine hydrochloride 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.
