Compared with other compounds in its class, the molecular weight of 255.70 g/mol gives 4-(1-(4-Chlorophenyl)-1H-pyrazol-5-yl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(1-(4-Chlorophenyl)-1H-pyrazol-5-yl)pyridine (CAS 1269292-71-8) is a high-purity analytical reference standard with the molecular formula C14H10ClN3 and a molecular weight of 255.70 g/mol.

Structurally, 4-(1-(4-Chlorophenyl)-1H-pyrazol-5-yl)pyridine (C14H10ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 255.70 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.
