Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Dimethyl 4-nitro-1H-pyrazole-3,5-dicarboxylate (CAS 59694-23-4), molecular formula C7H7N3O6 and molecular weight 229.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dimethyl 4-nitro-1H-pyrazole-3,5-dicarboxylate (C7H7N3O6) contains a carbohydrate-derived structure, an amide group. 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 229.15 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).
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.
