1,7-Dichloroheptane CAS 821-76-1 chemical structure

Description

1,7-Dichloroheptane (CAS 821-76-1) is a high-purity analytical reference standard with the molecular formula C7H14Cl2 and a molecular weight of 169.09 g/mol.

The molecular framework of 1,7-Dichloroheptane (C7H14Cl2) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-Dichloroheptane 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.
