Chemical Structure

Z-Phe-Phe-diazomethylketone CAS 65178-14-5 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Z-Phe-Phe-diazomethylketone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 470.52 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).

Z-Phe-Phe-diazomethylketone (CAS 65178-14-5) is a high-purity analytical reference standard with the molecular formula C27H26N4O4 and a molecular weight of 470.52 g/mol.

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), Z-Phe-Phe-diazomethylketone 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.
