5-(Chloromethyl)-3-phenyl-1H-pyrazole hydrochloride CAS 493038-58-7

Description

The occurrence of 5-(Chloromethyl)-3-phenyl-1H-pyrazole hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(Chloromethyl)-3-phenyl-1H-pyrazole hydrochloride (CAS 493038-58-7) is a high-purity analytical reference standard with the molecular formula C10H9ClN2HCl and a molecular weight of 229.10 g/mol.

Structurally, 5-(Chloromethyl)-3-phenyl-1H-pyrazole hydrochloride (C10H9ClN2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 229.10 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).

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.

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.
