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 1H-Pyrazole, 1-[[3-(phenylmethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-.
CATO supplies 1H-Pyrazole, 1-[[3-(phenylmethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- (CAS 1430750-52-9), a certified reference material (molecular formula C23H27BN2O3, MW 390.28 g/mol) for analytical method development and quality control.
The molecular framework of 1H-Pyrazole, 1-[[3-(phenylmethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- (C23H27BN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1H-Pyrazole, 1-[[3-(phenylmethoxy)phenyl]methyl]-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)- 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.
