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 (4-Chlorophenyl)dimethylsilanol.
CATO supplies (4-Chlorophenyl)dimethylsilanol (CAS 18246-04-3), a certified reference material (molecular formula C8H11ClOSi, MW 186.71 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H11ClOSi, (4-Chlorophenyl)dimethylsilanol contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (4-Chlorophenyl)dimethylsilanol 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.
