7-Methoxy-7-oxoheptanoic Acid CAS 20291-40-1

Description

Compared with other compounds in its class, the molecular weight of 174.19 g/mol gives 7-Methoxy-7-oxoheptanoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Methoxy-7-oxoheptanoic Acid (CAS 20291-40-1), molecular formula C8H14O4 and molecular weight 174.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 7-Methoxy-7-oxoheptanoic Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
