2-chloro-1-(8-fluoro-2,4-dihydrobenzo[5,6]thiino[4,3-c]pyrazol-2-yl)ethan-1-one CAS 259683-67-5

Description

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.

2-chloro-1-(8-fluoro-2,4-dihydrobenzo[5,6]thiino[4,3-c]pyrazol-2-yl)ethan-1-one (CAS 259683-67-5), molecular formula C12H8ClFN2OS and molecular weight 282.72 g/mol, is a CATO reference standard with documented purity and traceability.

2-chloro-1-(8-fluoro-2,4-dihydrobenzo[5,6]thiino[4,3-c]pyrazol-2-yl)ethan-1-one (C12H8ClFN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 2-chloro-1-(8-fluoro-2,4-dihydrobenzo[5,6]thiino[4,3-c]pyrazol-2-yl)ethan-1-one 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.
