Chemical Structure
Description
As a certified reference material (CRM), 1-Boc-4-(hydroxymethyl)pyrazole 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.
1-Boc-4-(hydroxymethyl)pyrazole (CAS 199003-22-0), molecular formula C9H14N2O3 and molecular weight 198.22 g/mol, is a CATO reference standard with documented purity and traceability.
1-Boc-4-(hydroxymethyl)pyrazole (C9H14N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
