Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-2-methyl-3,4'-bipyridine.
CATO supplies 6-Chloro-2-methyl-3,4'-bipyridine (CAS 88976-11-8), a certified reference material (molecular formula C11H9ClN2, MW 204.66 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 6-Chloro-2-methyl-3,4'-bipyridine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 6-Chloro-2-methyl-3,4'-bipyridine 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.
