Chemical Structure

3-(3,4-Dimethoxyphenyl)-5-methyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid CAS 1326815-47-7 chemical structure

Description

The occurrence of 3-(3,4-Dimethoxyphenyl)-5-methyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(3,4-Dimethoxyphenyl)-5-methyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid (CAS 1326815-47-7), a certified reference material (molecular formula C13H15NO5, MW 265.26 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-(3,4-Dimethoxyphenyl)-5-methyl-4,5-dihydro-1,2-oxazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 3-(3,4-Dimethoxyphenyl)-5-methyl-4,5-dihydro-1,2-oxazole-5-carboxylic 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.
