3,4-Dicyano-1H-pyrazole-5-carboxamide CAS 91195-30-1

Description

The occurrence of 3,4-Dicyano-1H-pyrazole-5-carboxamide is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,4-Dicyano-1H-pyrazole-5-carboxamide (CAS 91195-30-1) is a high-purity analytical reference standard with the molecular formula C6H3N5O and a molecular weight of 161.12 g/mol.

Structurally, 3,4-Dicyano-1H-pyrazole-5-carboxamide (C6H3N5O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 161.12 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).

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.
