2H,3H,4H,5H-naphtho[1,2-b]oxepin-5-one CAS 16563-58-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2H,3H,4H,5H-naphtho[1,2-b]oxepin-5-one.

2H,3H,4H,5H-naphtho[1,2-b]oxepin-5-one (CAS 16563-58-9) is a high-purity analytical reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.

Based on its molecular formula C14H12O2, 2H,3H,4H,5H-naphtho[1,2-b]oxepin-5-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 212.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2H,3H,4H,5H-naphtho[1,2-b]oxepin-5-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.
