5-Phenyl-1H-Tetrazole CAS 18039-42-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5-Phenyl-1H-Tetrazole (CAS 18039-42-4) is a high-purity analytical reference standard with the molecular formula C7H6N4 and a molecular weight of 146.15 g/mol.

Owing to a nitrile group, an aromatic ring system, 5-Phenyl-1H-Tetrazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 5-Phenyl-1H-Tetrazole 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.
