Chemical Structure
Description
As a certified reference material (CRM), n-[3-(4-tert-Butylbenzoyl)-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]-2-chloroacetamide 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.
CATO supplies n-[3-(4-tert-Butylbenzoyl)-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]-2-chloroacetamide (CAS 792954-19-9), a certified reference material (molecular formula C21H24ClNO2S, MW 389.94 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, n-[3-(4-tert-Butylbenzoyl)-4,5,6,7-tetrahydro-1-benzothiophen-2-yl]-2-chloroacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.94 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
