Description
As a certified reference material (CRM), Ethyl cyclohexa-2,5-diene-1-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.
Ethyl cyclohexa-2,5-diene-1-carboxylate (CAS 29246-24-0), molecular formula C9H12O2 and molecular weight 152.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl cyclohexa-2,5-diene-1-carboxylate (C9H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 152.19 g/mol, it falls into the medium-molecular-weight range. 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.
