Chemical Structure

1-(3-Methoxyphenyl)cyclopropanecarboxylic Acid CAS 74205-29-1 chemical structure

Description

The occurrence of 1-(3-Methoxyphenyl)cyclopropanecarboxylic 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.

1-(3-Methoxyphenyl)cyclopropanecarboxylic Acid (CAS 74205-29-1) is a high-purity analytical reference standard with the molecular formula C11H12O3 and a molecular weight of 192.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(3-Methoxyphenyl)cyclopropanecarboxylic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

CATO manufactures 1-(3-Methoxyphenyl)cyclopropanecarboxylic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
