Chemical Structure

1H-Indole-1-carboxylic acid, 2-borono-5-[[4-[[[(1,1-dimethylethyl)dimethylsilyl]oxy]methyl]-1-piperidinyl]methyl]-, 1-(1,1-dimethylethyl) ester CAS 913388-71-3 chemical structure

Description

1H-Indole-1-carboxylic acid, 2-borono-5-[[4-[[[(1,1-dimethylethyl)dimethylsilyl]oxy]methyl]-1-piperidinyl]methyl]-, 1-(1,1-dimethylethyl) ester (CAS 913388-71-3), molecular formula C26H43BN2O5Si and molecular weight 502.53 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1H-Indole-1-carboxylic acid, 2-borono-5-[[4-[[[(1,1-dimethylethyl)dimethylsilyl]oxy]methyl]-1-piperidinyl]methyl]-, 1-(1,1-dimethylethyl) ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 502.53 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.

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.
