5,8a-Dimethyl-3,4,8,8a-tetrahydro-1,6-(2H,7H)-naphthalenedione CAS 41019-71-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,8a-Dimethyl-3,4,8,8a-tetrahydro-1,6-(2H,7H)-naphthalenedione.

5,8a-Dimethyl-3,4,8,8a-tetrahydro-1,6-(2H,7H)-naphthalenedione (CAS 41019-71-0), molecular formula C12H16O2 and molecular weight 192.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5,8a-Dimethyl-3,4,8,8a-tetrahydro-1,6-(2H,7H)-naphthalenedione is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 5,8a-Dimethyl-3,4,8,8a-tetrahydro-1,6-(2H,7H)-naphthalenedione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
