rel-2-((1R,2R)-2-(tert-Butyl)cyclopropyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 749885-70-9

Description

Compared with other compounds in its class, the molecular weight of 224.15 g/mol gives rel-2-((1R,2R)-2-(tert-Butyl)cyclopropyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

rel-2-((1R,2R)-2-(tert-Butyl)cyclopropyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 749885-70-9) is a high-purity analytical reference standard with the molecular formula C13H25BO2 and a molecular weight of 224.15 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, rel-2-((1R,2R)-2-(tert-Butyl)cyclopropyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.15 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
