Chemical Structure
Description
As a certified reference material (CRM), Azetidin-1-yl(2-chlorothiazol-5-yl)methanone 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.
Azetidin-1-yl(2-chlorothiazol-5-yl)methanone (CAS 919784-27-3), molecular formula C7H7ClN2OS and molecular weight 202.66 g/mol, is a CATO reference standard with documented purity and traceability.
Azetidin-1-yl(2-chlorothiazol-5-yl)methanone (C7H7ClN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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).
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.
