Chemical Structure

3,4-Dimethylheptane CAS 922-28-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4-Dimethylheptane.

CATO supplies 3,4-Dimethylheptane (CAS 922-28-1), a certified reference material (molecular formula C9H20, MW 128.26 g/mol) for analytical method development and quality control.

The molecular framework of 3,4-Dimethylheptane (C9H20) 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.

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), 3,4-Dimethylheptane 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.
