Chemical Structure

H-Phe-Phe-OH CAS 2577-40-4 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 H-Phe-Phe-OH.

H-Phe-Phe-OH (CAS 2577-40-4) is a high-purity analytical reference standard with the molecular formula C18H20N2O3 and a molecular weight of 312.36 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, H-Phe-Phe-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), H-Phe-Phe-OH 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.
