Chemical Structure

m-PEG3-aldehyde CAS 356066-46-1 chemical structure

Description

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

m-PEG3-aldehyde (CAS 356066-46-1), molecular formula C8H16O4 and molecular weight 176.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, m-PEG3-aldehyde (C8H16O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 176.21 g/mol, it falls into the medium-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.
