Chemical Structure
Description
Cyclohex-3-en-1-yltrimethoxysilane (CAS 21619-76-1) is a high-purity analytical reference standard with the molecular formula C9H18O3Si and a molecular weight of 202.32 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Cyclohex-3-en-1-yltrimethoxysilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), Cyclohex-3-en-1-yltrimethoxysilane 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.
