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 1,1,4,4,7-Pentamethyl-3,4-dihydronaphthalen-2(1H)-one.
1,1,4,4,7-Pentamethyl-3,4-dihydronaphthalen-2(1H)-one (CAS 29020-85-7), molecular formula C15H20O and molecular weight 216.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1,4,4,7-Pentamethyl-3,4-dihydronaphthalen-2(1H)-one (C15H20O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 1,1,4,4,7-Pentamethyl-3,4-dihydronaphthalen-2(1H)-one 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.
