Chemical Structure

1,7-Dibromo-1,2,3,4-tetrahydronaphthalene CAS 1341347-05-4 chemical structure

Description

The occurrence of 1,7-Dibromo-1,2,3,4-tetrahydronaphthalene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,7-Dibromo-1,2,3,4-tetrahydronaphthalene (CAS 1341347-05-4), molecular formula C10H10Br2 and molecular weight 289.99 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to bromine substitution, an aromatic ring system, 1,7-Dibromo-1,2,3,4-tetrahydronaphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 1,7-Dibromo-1,2,3,4-tetrahydronaphthalene 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.
