Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.72 g/mol gives 4-Chlorophenothiazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chlorophenothiazine (CAS 7369-69-9), molecular formula C12H8ClNS and molecular weight 233.72 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chlorophenothiazine (C12H8ClNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Chlorophenothiazine 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.
