{[1-(pyridin-3-yl)ethylidene]amino}urea CAS 6335-40-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including {[1-(pyridin-3-yl)ethylidene]amino}urea.

{[1-(pyridin-3-yl)ethylidene]amino}urea (CAS 6335-40-6), molecular formula C8H10N4O and molecular weight 178.19 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-(pyridin-3-yl)ethylidene]amino}urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.19 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-(pyridin-3-yl)ethylidene]amino}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.
