1-{[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzene]sulfonyl}pyrazole CAS 2096997-00-9 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 1-{[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzene]sulfonyl}pyrazole.

CATO supplies 1-{[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzene]sulfonyl}pyrazole (CAS 2096997-00-9), a certified reference material (molecular formula C15H19BN2O4S, MW 334.20 g/mol) for analytical method development and quality control.

Structurally, 1-{[4-(tetramethyl-1,3,2-dioxaborolan-2-yl)benzene]sulfonyl}pyrazole (C15H19BN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.5, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 334.20 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
