Chemical Structure
Description
The occurrence of 1,3,3-Trimethyl-2-methylidenebicyclo[2.2.1]heptane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,3,3-Trimethyl-2-methylidenebicyclo[2.2.1]heptane (CAS 13567-57-2), a certified reference material (molecular formula C11H18, MW 150.26 g/mol) for analytical method development and quality control.
The molecular framework of 1,3,3-Trimethyl-2-methylidenebicyclo[2.2.1]heptane (C11H18) is characterized by an organic framework. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
