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 2-Nitrobenzofuran-5-ol.
2-Nitrobenzofuran-5-ol (CAS 40024-32-6) is a high-purity analytical reference standard with the molecular formula C9H14N5O13P3 and a molecular weight of 493.15 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, 2-Nitrobenzofuran-5-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 493.15 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), 2-Nitrobenzofuran-5-ol 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.
