Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 18:1 PI (3) P.
18:1 PI (3) P (CAS 1246303-09-2) is a high-purity analytical reference standard with the molecular formula C45H82O16P2H4N and a molecular weight of 959.12 g/mol.
Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, 18:1 PI (3) P is typically white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 959.12 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.
As a certified reference material (CRM), 18:1 PI (3) P meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
