Chemical Structure
Description
The occurrence of 2-(Dichloromethyl)-4-methylpyridine is closely related to a nitrile group, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(Dichloromethyl)-4-methylpyridine (CAS 88237-12-1), a certified reference material (molecular formula C7H7Cl2N, MW 176.04 g/mol) for analytical method development and quality control.
Structurally, 2-(Dichloromethyl)-4-methylpyridine (C7H7Cl2N) contains a nitrile group, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 176.04 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
