Chemical Structure

Ethyl 2,3-dihydrospiro[indene-1,2'-oxirane]-3'-carboxylate CAS 67197-73-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 218.25 g/mol gives Ethyl 2,3-dihydrospiro[indene-1,2'-oxirane]-3'-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2,3-dihydrospiro[indene-1,2'-oxirane]-3'-carboxylate (CAS 67197-73-3), molecular formula C13H14O3 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 2,3-dihydrospiro[indene-1,2'-oxirane]-3'-carboxylate (C13H14O3) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Ethyl 2,3-dihydrospiro[indene-1,2'-oxirane]-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.
