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-(5-Bromo-6-methoxynaphthalen-2-yl)propan-1-one.
1-(5-Bromo-6-methoxynaphthalen-2-yl)propan-1-one (CAS 92189-66-7), molecular formula C14H13BrO2 and molecular weight 293.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 1-(5-Bromo-6-methoxynaphthalen-2-yl)propan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.16 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 1-(5-Bromo-6-methoxynaphthalen-2-yl)propan-1-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.
