Description
As a certified reference material (CRM), 4-Acetyl-6-cyanopyridine-2-sulfonyl chloride 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.
4-Acetyl-6-cyanopyridine-2-sulfonyl chloride (CAS 1393547-13-1) is a high-purity analytical reference standard with the molecular formula C8H5ClN2O3S and a molecular weight of 244.65 g/mol.
The molecular framework of 4-Acetyl-6-cyanopyridine-2-sulfonyl chloride (C8H5ClN2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
