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-(3-Chloro-2-fluorophenyl)-2-methylbut-3-yn-2-ol.
4-(3-Chloro-2-fluorophenyl)-2-methylbut-3-yn-2-ol (CAS 1187385-72-3), molecular formula C11H10ClFO and molecular weight 212.65 g/mol, is a CATO reference standard with documented purity and traceability.
4-(3-Chloro-2-fluorophenyl)-2-methylbut-3-yn-2-ol (C11H10ClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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-(3-Chloro-2-fluorophenyl)-2-methylbut-3-yn-2-ol 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.
