Chemical Structure

聚乙二醇400 CAS 5322-68-3 chemical structure

Description

聚乙二醇400 (CAS 5322-68-3), molecular formula C10H22O3 and molecular weight 190.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 聚乙二醇400 (C10H22O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 190.28 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures 聚乙二醇400 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
