Chemical Structure
Description
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.
n-((1-Aminocyclohexyl)methyl)thiophene-2-sulfonamide (CAS 1153056-78-0) is a high-purity analytical reference standard with the molecular formula C11H18N2O2S2 and a molecular weight of 274.40 g/mol.
The molecular framework of n-((1-Aminocyclohexyl)methyl)thiophene-2-sulfonamide (C11H18N2O2S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), n-((1-Aminocyclohexyl)methyl)thiophene-2-sulfonamide 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.
