Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 400.47 g/mol gives Polyethylene Terephthalate G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Polyethylene Terephthalate G (CAS 25640-14-6), molecular formula C10H10O4C8H16O2C2H6O2 and molecular weight 400.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Polyethylene Terephthalate G is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Polyethylene Terephthalate G 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.
