The occurrence of Dimethylsila-14-crown-5 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Dimethylsila-14-crown-5 (CAS 70851-49-9), a certified reference material (molecular formula C10H22O5Si, MW 250.36 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dimethylsila-14-crown-5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.36 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), Dimethylsila-14-crown-5 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.
