5-(3,4-Dimethoxyphenyl)pentanoic acid CAS 1145-15-9

Description

The occurrence of 5-(3,4-Dimethoxyphenyl)pentanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(3,4-Dimethoxyphenyl)pentanoic acid (CAS 1145-15-9), a certified reference material (molecular formula C13H18O4, MW 238.28 g/mol) for analytical method development and quality control.

Structurally, 5-(3,4-Dimethoxyphenyl)pentanoic acid (C13H18O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 238.28 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.

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), 5-(3,4-Dimethoxyphenyl)pentanoic 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.
