1,3-bis[1-(2-methylpropyl)-1H-pyrazol-5-yl]urea CAS 1311313-58-2

Description

The occurrence of 1,3-bis[1-(2-methylpropyl)-1H-pyrazol-5-yl]urea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,3-bis[1-(2-methylpropyl)-1H-pyrazol-5-yl]urea (CAS 1311313-58-2) is a high-purity analytical reference standard with the molecular formula C15H24N6O and a molecular weight of 304.39 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,3-bis[1-(2-methylpropyl)-1H-pyrazol-5-yl]urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.39 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).

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), 1,3-bis[1-(2-methylpropyl)-1H-pyrazol-5-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.
