Chemical Structure

3,6,9,12,15,18,21-Heptaoxatricosan-1-ol CAS 4435-25-0 chemical structure

Description

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.

3,6,9,12,15,18,21-Heptaoxatricosan-1-ol (CAS 4435-25-0), molecular formula C16H34O8 and molecular weight 354.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3,6,9,12,15,18,21-Heptaoxatricosan-1-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.44 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.
