Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.63 g/mol gives 4-Pyridineacetonitrile, 2-chloro-α,α-dimethyl- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Pyridineacetonitrile, 2-chloro-α,α-dimethyl- (CAS 2091129-67-6) is a high-purity analytical reference standard with the molecular formula C9H9ClN2 and a molecular weight of 180.63 g/mol.
4-Pyridineacetonitrile, 2-chloro-α,α-dimethyl- (C9H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 4-Pyridineacetonitrile, 2-chloro-α,α-dimethyl- 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.
