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 Ethyl 2-methyl-5-(p-tolyl)furan-3-carboxylate.
Ethyl 2-methyl-5-(p-tolyl)furan-3-carboxylate (CAS 4302-54-9), molecular formula C15H16O3 and molecular weight 244.29 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 2-methyl-5-(p-tolyl)furan-3-carboxylate (C15H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 244.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Ethyl 2-methyl-5-(p-tolyl)furan-3-carboxylate 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.
