Chemical Structure
Description
2-(1,3-Benzoxazol-2-ylsulfanyl)-N-(3,4-dichlorophenyl)acetamide (CAS 297150-39-1), molecular formula C15H10Cl2N2O2S and molecular weight 353.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(1,3-Benzoxazol-2-ylsulfanyl)-N-(3,4-dichlorophenyl)acetamide (C15H10Cl2N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 353.22 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
As a certified reference material (CRM), 2-(1,3-Benzoxazol-2-ylsulfanyl)-N-(3,4-dichlorophenyl)acetamide 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.
