Chemical Structure

4,4'-Oxydibutanoic acid CAS 7423-25-8 chemical structure

Description

4,4'-Oxydibutanoic acid (CAS 7423-25-8) is a high-purity analytical reference standard with the molecular formula C8H14O5 and a molecular weight of 190.19 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4'-Oxydibutanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
