(E)-4,4,5,5-Tetramethyl-2-(penta-2,4-dien-1-yl)-1,3,2-dioxaborolane CAS 102787-31-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4,4,5,5-Tetramethyl-2-(penta-2,4-dien-1-yl)-1,3,2-dioxaborolane.

(E)-4,4,5,5-Tetramethyl-2-(penta-2,4-dien-1-yl)-1,3,2-dioxaborolane (CAS 102787-31-5) is a high-purity analytical reference standard with the molecular formula C11H19BO2 and a molecular weight of 194.08 g/mol.

Based on its molecular formula C11H19BO2, (E)-4,4,5,5-Tetramethyl-2-(penta-2,4-dien-1-yl)-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 194.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), (E)-4,4,5,5-Tetramethyl-2-(penta-2,4-dien-1-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.
