Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-N-(7-methyl-9-oxo-9H-thioxanthen-2-yl)benzamide 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.
CATO supplies 2-Chloro-N-(7-methyl-9-oxo-9H-thioxanthen-2-yl)benzamide (CAS 860610-00-0), a certified reference material (molecular formula C21H14ClNO2S, MW 379.86 g/mol) for analytical method development and quality control.
Structurally, 2-Chloro-N-(7-methyl-9-oxo-9H-thioxanthen-2-yl)benzamide (C21H14ClNO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 379.86 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
