Chemical Structure
Description
As a certified reference material (CRM), (2-Chlorothiazol-4-yl)methanamine 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-Chlorothiazol-4-yl)methanamine (CAS 139425-75-5), molecular formula C4H5ClN2S and molecular weight 148.61 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Chlorothiazol-4-yl)methanamine (C4H5ClN2S) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
