Chemical Structure

1,4-Dimethylpyridinium Chloride CAS 38078-47-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,4-Dimethylpyridinium Chloride (CAS 38078-47-6) is a high-purity analytical reference standard with the molecular formula C7H10NCl and a molecular weight of 143.61 g/mol.

Owing to a nitrile group, chlorine substitution, 1,4-Dimethylpyridinium Chloride is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
