Description

CATO supplies 2-Chloropyridine-5-acetonitrile 2-(6-chloropyridin-3-yl)acetonitrile 2-(6-chloro-3-pyridinyl)acetonitrile 2-chloro-5-pyridineacetonitrile (6-chloro-pyridin-3-yl)-acetonitrile 6-Chloro-3-pyridylacetonitrile 2-Chloro-5-(cyanomethyl)pyridine 39891-09-3 (CAS 39891-09-3), a certified reference material (molecular formula C7H11ClN2, MW 158.63 g/mol) for analytical method development and quality control.

Structurally, 2-Chloropyridine-5-acetonitrile 2-(6-chloropyridin-3-yl)acetonitrile 2-(6-chloro-3-pyridinyl)acetonitrile 2-chloro-5-pyridineacetonitrile (6-chloro-pyridin-3-yl)-acetonitrile 6-Chloro-3-pyridylacetonitrile 2-Chloro-5-(cyanomethyl)pyridine 39891-09-3 (C7H11ClN2) 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 158.63 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).

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

As a certified reference material (CRM), 2-Chloropyridine-5-acetonitrile 2-(6-chloropyridin-3-yl)acetonitrile 2-(6-chloro-3-pyridinyl)acetonitrile 2-chloro-5-pyridineacetonitrile (6-chloro-pyridin-3-yl)-acetonitrile 6-Chloro-3-pyridylacetonitrile 2-Chloro-5-(cyanomethyl)pyridine 39891-09-3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
