Chemical Structure
Description
The occurrence of 1,5-Pentanediol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Pentanediol (CAS 111-29-5), molecular formula C5H12O2 and molecular weight 104.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,5-Pentanediol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.15 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.
CATO manufactures 1,5-Pentanediol 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.
