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-Chloro-1-(trimethylsilyl)pent-1-yn-3-one.
4-Chloro-1-(trimethylsilyl)pent-1-yn-3-one (CAS 914358-91-1) is a high-purity analytical reference standard with the molecular formula C8H13ClOSi and a molecular weight of 188.73 g/mol.
4-Chloro-1-(trimethylsilyl)pent-1-yn-3-one (C8H13ClOSi) contains a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Chloro-1-(trimethylsilyl)pent-1-yn-3-one 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.
