3-Benzamido-N-(4-methylbenzyl)thiophene-2-carboxamide CAS 439120-53-3

Description

3-Benzamido-N-(4-methylbenzyl)thiophene-2-carboxamide (CAS 439120-53-3), molecular formula C20H18N2O2S and molecular weight 350.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Benzamido-N-(4-methylbenzyl)thiophene-2-carboxamide (C20H18N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 350.43 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), 3-Benzamido-N-(4-methylbenzyl)thiophene-2-carboxamide 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.
