Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((1-Ethyl-1h-pyrazol-5-yl)methoxy)aniline.
4-((1-Ethyl-1h-pyrazol-5-yl)methoxy)aniline (CAS 1262865-33-7), molecular formula C12H15N3O and molecular weight 217.27 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, 4-((1-Ethyl-1h-pyrazol-5-yl)methoxy)aniline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 217.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((1-Ethyl-1h-pyrazol-5-yl)methoxy)aniline 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.
