Chemical Structure

N-Heptane CAS 142-82-5 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.

N-Heptane (CAS 142-82-5) is a high-purity analytical reference standard with the molecular formula C7H16 and a molecular weight of 100.20 g/mol.

The molecular framework of N-Heptane (C7H16) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

As a certified reference material (CRM), N-Heptane 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.
