Chemical Structure
Description
As a certified reference material (CRM), 4-(Chloromethyl)-2-[(4-chlorophenyl)methyl]-1,3-thiazole 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.
4-(Chloromethyl)-2-[(4-chlorophenyl)methyl]-1,3-thiazole (CAS 73765-41-0), molecular formula C11H9Cl2NS and molecular weight 258.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 4-(Chloromethyl)-2-[(4-chlorophenyl)methyl]-1,3-thiazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
