Chemical Structure
Description
As a certified reference material (CRM), 2-(6-Chloronaphthalen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
2-(6-Chloronaphthalen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 870822-85-8), molecular formula C16H18BClO2 and molecular weight 288.58 g/mol, is a CATO reference standard with documented purity and traceability.
2-(6-Chloronaphthalen-2-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C16H18BClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
