tert-Butyl(2,3-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)dimethylsilane CAS 2818962-13-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 403.22 g/mol gives tert-Butyl(2,3-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)dimethylsilane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl(2,3-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)dimethylsilane (CAS 2818962-13-7) is a high-purity analytical reference standard with the molecular formula C18H29BCl2O3Si and a molecular weight of 403.22 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, tert-Butyl(2,3-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)dimethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), tert-Butyl(2,3-dichloro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)dimethylsilane 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.
