Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-(2,4-difluorophenyl) 5,6-dichloropyridine-3-carbothioate.
CATO supplies S-(2,4-difluorophenyl) 5,6-dichloropyridine-3-carbothioate (CAS 680216-39-1), a certified reference material (molecular formula C12H5Cl2F2NOS, MW 320.14 g/mol) for analytical method development and quality control.
Structurally, S-(2,4-difluorophenyl) 5,6-dichloropyridine-3-carbothioate (C12H5Cl2F2NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 320.14 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), S-(2,4-difluorophenyl) 5,6-dichloropyridine-3-carbothioate 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.
