2-Ethyl-4-methoxy-5-methyl-3-oxoheptanedioic acid CAS 58700-99-5

Description

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.

2-Ethyl-4-methoxy-5-methyl-3-oxoheptanedioic acid (CAS 58700-99-5) is a high-purity analytical reference standard with the molecular formula C7H10O4 and a molecular weight of 158.15 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Ethyl-4-methoxy-5-methyl-3-oxoheptanedioic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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).

As a certified reference material (CRM), 2-Ethyl-4-methoxy-5-methyl-3-oxoheptanedioic 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.
