Chemical Structure

1-Chloro-5,8-dimethyl-1,2,3,4-tetrahydronaphthalene CAS 1082399-52-7 chemical structure

Description

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.

1-Chloro-5,8-dimethyl-1,2,3,4-tetrahydronaphthalene (CAS 1082399-52-7), molecular formula C12H15Cl and molecular weight 194.70 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Chloro-5,8-dimethyl-1,2,3,4-tetrahydronaphthalene (C12H15Cl) is characterized by chlorine substitution, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
