Chemical Structure
Description
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.
(E)-N-(3,4-dichlorophenyl)-1-(1-(thiazol-2-yl)-1H-pyrrol-2-yl)methanimine (CAS 691873-18-4), molecular formula C14H9Cl2N3S and molecular weight 322.21 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-N-(3,4-dichlorophenyl)-1-(1-(thiazol-2-yl)-1H-pyrrol-2-yl)methanimine (C14H9Cl2N3S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (E)-N-(3,4-dichlorophenyl)-1-(1-(thiazol-2-yl)-1H-pyrrol-2-yl)methanimine 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.
