Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 12-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3,6,7-tetrahydro-1H,3'H,5H-spiro[chromeno[2,3-f]pyrido[3,2,1-ij]quinoline-9,1'-isobenzofuran]-3'-one.
12-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3,6,7-tetrahydro-1H,3'H,5H-spiro[chromeno[2,3-f]pyrido[3,2,1-ij]quinoline-9,1'-isobenzofuran]-3'-one (CAS 1199576-10-7) is a high-purity analytical reference standard with the molecular formula C32H32BNO5 and a molecular weight of 521.41 g/mol.
The molecular framework of 12-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3,6,7-tetrahydro-1H,3'H,5H-spiro[chromeno[2,3-f]pyrido[3,2,1-ij]quinoline-9,1'-isobenzofuran]-3'-one (C32H32BNO5) is characterized by a nitrogen-containing heterocyclic scaffold, 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), 12-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3,6,7-tetrahydro-1H,3'H,5H-spiro[chromeno[2,3-f]pyrido[3,2,1-ij]quinoline-9,1'-isobenzofuran]-3'-one 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.
