Chemical Structure
Description
The occurrence of 4-Chloro-2-isopropylpyridine hydrobromide is closely related to a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Chloro-2-isopropylpyridine hydrobromide (CAS 98420-97-4), a certified reference material (molecular formula C8H10ClNHBr, MW 236.54 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-2-isopropylpyridine hydrobromide (C8H10ClNHBr) contains a nitrile group, chlorine/bromine 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 236.54 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
