Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-7-methoxy-4-(pyridin-3-yl)-4H-chromene-3-carbonitrile.

2-Amino-7-methoxy-4-(pyridin-3-yl)-4H-chromene-3-carbonitrile (CAS 475576-65-9) is a high-purity analytical reference standard with the molecular formula C16H13N3O2 and a molecular weight of 279.29 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Amino-7-methoxy-4-(pyridin-3-yl)-4H-chromene-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.29 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.

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), 2-Amino-7-methoxy-4-(pyridin-3-yl)-4H-chromene-3-carbonitrile 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.
