Chemical Structure
Description
tert-Butyl 3-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methylene)pyrrolidine-1-carboxylate (CAS 2376764-71-3), molecular formula C16H28BNO4 and molecular weight 309.21 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl 3-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methylene)pyrrolidine-1-carboxylate (C16H28BNO4) contains an amide group, a carboxylic acid 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.
As a certified reference material (CRM), tert-Butyl 3-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methylene)pyrrolidine-1-carboxylate 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.
