Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4,5,5-Tetramethyl-2-[spiro[4.5]dec-7-en-8-yl]-1,3,2-dioxaborolane.
4,4,5,5-Tetramethyl-2-[spiro[4.5]dec-7-en-8-yl]-1,3,2-dioxaborolane (CAS 859219-41-3), molecular formula C16H27BO2 and molecular weight 262.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-[spiro[4.5]dec-7-en-8-yl]-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4,4,5,5-Tetramethyl-2-[spiro[4.5]dec-7-en-8-yl]-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.
