Compared with other compounds in its class, the molecular weight of 120.11 g/mol gives Tetrazolo[1,5-a]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetrazolo[1,5-a]pyridine (CAS 274-87-3) is a high-purity analytical reference standard with the molecular formula C5H4N4 and a molecular weight of 120.11 g/mol.
Owing to a nitrile group, Tetrazolo[1,5-a]pyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Tetrazolo[1,5-a]pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
