Chemical Structure
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.
CATO supplies 2-Chloro-1-(4a,10a-dihydro-10H-phenothiazin-10-yl)ethan-1-one (CAS 701920-71-0), a certified reference material (molecular formula C14H12ClNOS, MW 277.77 g/mol) for analytical method development and quality control.
2-Chloro-1-(4a,10a-dihydro-10H-phenothiazin-10-yl)ethan-1-one (C14H12ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-Chloro-1-(4a,10a-dihydro-10H-phenothiazin-10-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.
