Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Aminomethylene)-2H-1-benzopyran-2,4(3H)-dione.
3-(Aminomethylene)-2H-1-benzopyran-2,4(3H)-dione (CAS 1189755-26-7) is a high-purity analytical reference standard with the molecular formula C10H7NO3 and a molecular weight of 189.17 g/mol.
The molecular framework of 3-(Aminomethylene)-2H-1-benzopyran-2,4(3H)-dione (C10H7NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-(Aminomethylene)-2H-1-benzopyran-2,4(3H)-dione 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.
