Description
As a certified reference material (CRM), 1-[2-(4-methylpiperidin-1-yl)-2-(thiophen-2-yl)ethyl]-3-[(5-sulfamoylthiophen-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.
1-[2-(4-methylpiperidin-1-yl)-2-(thiophen-2-yl)ethyl]-3-[(5-sulfamoylthiophen-2-yl)methyl]urea (CAS 941384-56-1) is a high-purity analytical reference standard with the molecular formula C18H26N4O3S3 and a molecular weight of 442.62 g/mol.
The molecular framework of 1-[2-(4-methylpiperidin-1-yl)-2-(thiophen-2-yl)ethyl]-3-[(5-sulfamoylthiophen-2-yl)methyl]urea (C18H26N4O3S3) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
