1,2,3,4-Tetrahydro-naphthalene-2,3-dicarboxylic acid CAS 78239-36-8

Description

Compared with other compounds in its class, the molecular weight of 220.22 g/mol gives 1,2,3,4-Tetrahydro-naphthalene-2,3-dicarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2,3,4-Tetrahydro-naphthalene-2,3-dicarboxylic acid (CAS 78239-36-8) is a high-purity analytical reference standard with the molecular formula C12H12O4 and a molecular weight of 220.22 g/mol.

Structurally, 1,2,3,4-Tetrahydro-naphthalene-2,3-dicarboxylic acid (C12H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 220.22 g/mol, it falls into the medium-molecular-weight range. 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.
