Description

Compared with other compounds in its class, the molecular weight of 336.45 g/mol gives 3-[(6-Ethoxy-3,4-dihydrospiro[chromene-2,1-cyclopentan]-4-yl)thio]propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-[(6-Ethoxy-3,4-dihydrospiro[chromene-2,1-cyclopentan]-4-yl)thio]propanoic acid (CAS 1171515-79-9), a certified reference material (molecular formula C18H24O4S, MW 336.45 g/mol) for analytical method development and quality control.

Structurally, 3-[(6-Ethoxy-3,4-dihydrospiro[chromene-2,1-cyclopentan]-4-yl)thio]propanoic acid (C18H24O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 336.45 g/mol, it falls into the moderately-high-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), 3-[(6-Ethoxy-3,4-dihydrospiro[chromene-2,1-cyclopentan]-4-yl)thio]propanoic 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.
