Description
As a certified reference material (CRM), 5-tert-Butyl-2-chloropyridine-3-carbonitrile 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.
5-tert-Butyl-2-chloropyridine-3-carbonitrile (CAS 2090976-29-5), molecular formula C10H11ClN2 and molecular weight 194.66 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-tert-Butyl-2-chloropyridine-3-carbonitrile (C10H11ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
