1-((5-(Furan-2-yl)-1-(2-methoxyethyl)-1H-pyrazol-3-yl)methyl)-3-(thiophen-2-yl)urea CAS 1421505-40-9

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.

1-((5-(Furan-2-yl)-1-(2-methoxyethyl)-1H-pyrazol-3-yl)methyl)-3-(thiophen-2-yl)urea (CAS 1421505-40-9), molecular formula C16H18N4O3S and molecular weight 346.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-((5-(Furan-2-yl)-1-(2-methoxyethyl)-1H-pyrazol-3-yl)methyl)-3-(thiophen-2-yl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 1-((5-(Furan-2-yl)-1-(2-methoxyethyl)-1H-pyrazol-3-yl)methyl)-3-(thiophen-2-yl)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.
