Chemical Structure
Description
The occurrence of 3-Chloro-3-methyloctane is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-3-methyloctane (CAS 28320-88-9), molecular formula C9H19Cl and molecular weight 162.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine substitution, 3-Chloro-3-methyloctane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3-Chloro-3-methyloctane 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.
