Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-(Tert-butyl)benzyl)oxy)-N-(3,4-dichlorophenyl)thiophene-2-carboxamide.
3-((4-(Tert-butyl)benzyl)oxy)-N-(3,4-dichlorophenyl)thiophene-2-carboxamide (CAS 344270-52-6) is a high-purity analytical reference standard with the molecular formula C22H21Cl2NO2S and a molecular weight of 434.38 g/mol.
Structurally, 3-((4-(Tert-butyl)benzyl)oxy)-N-(3,4-dichlorophenyl)thiophene-2-carboxamide (C22H21Cl2NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 434.38 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-((4-(Tert-butyl)benzyl)oxy)-N-(3,4-dichlorophenyl)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.
