Benzyl 3-(hydroxy((3-hydroxy-2,3-dimethylbutan-2-yl)oxy)boranyl)-2,5-dihydro-1H-pyrrole-1-carboxylate CAS 2227133-31-3 chemical structure

Description

The occurrence of Benzyl 3-(hydroxy((3-hydroxy-2,3-dimethylbutan-2-yl)oxy)boranyl)-2,5-dihydro-1H-pyrrole-1-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Benzyl 3-(hydroxy((3-hydroxy-2,3-dimethylbutan-2-yl)oxy)boranyl)-2,5-dihydro-1H-pyrrole-1-carboxylate (CAS 2227133-31-3) is a high-purity analytical reference standard with the molecular formula C18H26BNO5 and a molecular weight of 347.21 g/mol.

Benzyl 3-(hydroxy((3-hydroxy-2,3-dimethylbutan-2-yl)oxy)boranyl)-2,5-dihydro-1H-pyrrole-1-carboxylate (C18H26BNO5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
