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 2,6-Dimethyl-3-heptene (cis & trans).
2,6-Dimethyl-3-heptene (cis & trans) (CAS 2738-18-3), molecular formula C9H18 and molecular weight 126.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dimethyl-3-heptene (cis & trans) (C9H18) 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.
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.
