Chemical Structure

10H-Phenothiazine 5-oxide CAS 1207-71-2 chemical structure

Description

As a certified reference material (CRM), 10H-Phenothiazine 5-oxide 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.

10H-Phenothiazine 5-oxide (CAS 1207-71-2) is a high-purity analytical reference standard with the molecular formula C12H9NOS and a molecular weight of 215.27 g/mol.

Based on its molecular formula C12H9NOS, 10H-Phenothiazine 5-oxide contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
