Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 117.57 g/mol gives 3-Chloropyridine-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloropyridine-d4 (CAS 1001003-95-7), molecular formula C5D4ClN and molecular weight 117.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a nitrile group, chlorine substitution, 3-Chloropyridine-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 117.57 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).
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.
