Chemical Structure
Description
The occurrence of 18:0 PG-d70 is closely related to deuterium isotope labeling, a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
18:0 PG-d70 (CAS 326495-47-0), molecular formula C23H13D34O7P and molecular weight 500.80 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage, 18:0 PG-d70 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.80 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 18:0 PG-d70 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.
