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-(2-Methoxyphenyl)-3-(pyrazolo[1,5-a]pyridin-3-ylmethyl)urea (CAS 1396748-99-4), molecular formula C16H16N4O2 and molecular weight 296.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(2-Methoxyphenyl)-3-(pyrazolo[1,5-a]pyridin-3-ylmethyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.32 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-(2-Methoxyphenyl)-3-(pyrazolo[1,5-a]pyridin-3-ylmethyl)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.
