Description

As a certified reference material (CRM), 2-chloro-N-(5,5-dimethyl-7-oxo-4,6-dihydrobenzothiazol-2-yl)benzamide 5969-19-7 CTK1H1920 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.

2-chloro-N-(5,5-dimethyl-7-oxo-4,6-dihydrobenzothiazol-2-yl)benzamide 5969-19-7 CTK1H1920 (CAS 5969-19-7) is a high-purity analytical reference standard with the molecular formula C15H16O5 and a molecular weight of 276.28 g/mol.

The molecular framework of 2-chloro-N-(5,5-dimethyl-7-oxo-4,6-dihydrobenzothiazol-2-yl)benzamide 5969-19-7 CTK1H1920 (C15H16O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
