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-Ethoxy-5-(methoxycarbonyl)benzoic acid.
3-Ethoxy-5-(methoxycarbonyl)benzoic acid (CAS 706792-00-9) is a high-purity analytical reference standard with the molecular formula C11H12O5 and a molecular weight of 224.21 g/mol.
The molecular framework of 3-Ethoxy-5-(methoxycarbonyl)benzoic acid (C11H12O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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-Ethoxy-5-(methoxycarbonyl)benzoic 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.
