(R)-3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(trimethylsilyl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-5-ol (CAS 2135831-71-7), molecular formula C15H27BN2O3Si and molecular weight 322.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (R)-3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2-(trimethylsilyl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-5-ol (C15H27BN2O3Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 322.28 g/mol, it falls into the moderately-high-molecular-weight range. 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.
