Description
4-(Ethoxycarbonyl)-3-methoxybenzoic acid (CAS 5462-88-4) is a high-purity analytical reference standard with the molecular formula C19H26N5O11P and a molecular weight of 531.41 g/mol.
Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, 4-(Ethoxycarbonyl)-3-methoxybenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 531.41 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), 4-(Ethoxycarbonyl)-3-methoxybenzoic acid 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.
