Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 168.30 g/mol gives 1,8-Dimethylnaphthalene-d12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,8-Dimethylnaphthalene-d12 (CAS 104489-29-4), molecular formula C12D12 and molecular weight 168.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,8-Dimethylnaphthalene-d12 (C12D12) is characterized by deuterium isotope labeling, 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
