Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloropyridin-2-ol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.54 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.
6-Chloropyridin-2-ol (CAS 73018-09-4), molecular formula C5H4ClNO and molecular weight 129.54 g/mol, is a CATO reference standard with documented purity and traceability.
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-Chloropyridin-2-ol 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.
