Chemical Structure

1-(2-Benzothiazolyl)-2-phenylethanone CAS 220753-47-9 chemical structure

Description

1-(2-Benzothiazolyl)-2-phenylethanone (CAS 220753-47-9) is a high-purity analytical reference standard with the molecular formula C15H11NOS and a molecular weight of 253.32 g/mol.

Structurally, 1-(2-Benzothiazolyl)-2-phenylethanone (C15H11NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 253.32 g/mol, it falls into the medium-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.

As a certified reference material (CRM), 1-(2-Benzothiazolyl)-2-phenylethanone 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.
