Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 5-(4,4,6-trimethyl-1,3,2-dioxaborinan-2-yl)-1H-pyrazole-1-carboxylate.
tert-Butyl 5-(4,4,6-trimethyl-1,3,2-dioxaborinan-2-yl)-1H-pyrazole-1-carboxylate (CAS 2096998-50-2), molecular formula C14H23BN2O4 and molecular weight 294.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, tert-Butyl 5-(4,4,6-trimethyl-1,3,2-dioxaborinan-2-yl)-1H-pyrazole-1-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.15 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.
As a certified reference material (CRM), tert-Butyl 5-(4,4,6-trimethyl-1,3,2-dioxaborinan-2-yl)-1H-pyrazole-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.
