Chemical Structure
Description
The occurrence of 3-(Chloromethyl)-1-(2-methylpropyl)-1h-pyrazole is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(Chloromethyl)-1-(2-methylpropyl)-1h-pyrazole (CAS 1824054-77-4), molecular formula C8H13ClN2 and molecular weight 172.66 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Chloromethyl)-1-(2-methylpropyl)-1h-pyrazole (C8H13ClN2) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 172.66 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.
