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 1-Cyclopentyl-3-((5-(thiophene-3-carbonyl)thiophen-2-yl)methyl)urea.
1-Cyclopentyl-3-((5-(thiophene-3-carbonyl)thiophen-2-yl)methyl)urea (CAS 1797141-57-1), molecular formula C16H18N2O2S2 and molecular weight 334.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Cyclopentyl-3-((5-(thiophene-3-carbonyl)thiophen-2-yl)methyl)urea (C16H18N2O2S2) 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.
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), 1-Cyclopentyl-3-((5-(thiophene-3-carbonyl)thiophen-2-yl)methyl)urea 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.
