Chemical Structure

7-Oxoheptanoic acid CAS 35923-65-0 chemical structure

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.

7-Oxoheptanoic acid (CAS 35923-65-0) is a high-purity analytical reference standard with the molecular formula C7H12O3 and a molecular weight of 144.17 g/mol.

Structurally, 7-Oxoheptanoic acid (C7H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 144.17 g/mol, it falls into the low-molecular-weight range.

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.
