Chemical Structure

1-(1-Methyl-1h-tetrazol-5-yl)-ethanone CAS 185445-05-0 chemical structure

Description

1-(1-Methyl-1h-tetrazol-5-yl)-ethanone (CAS 185445-05-0), molecular formula C4H6N4O and molecular weight 126.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(1-Methyl-1h-tetrazol-5-yl)-ethanone (C4H6N4O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 126.12 g/mol, it falls into the low-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).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
