Chemical Structure

1-tert-Butyl 2-ethyl 4-bromo-1H-pyrrolo[2,3-b]pyridine-1,2-dicarboxylate CAS 1269449-33-3 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-tert-Butyl 2-ethyl 4-bromo-1H-pyrrolo[2,3-b]pyridine-1,2-dicarboxylate.

1-tert-Butyl 2-ethyl 4-bromo-1H-pyrrolo[2,3-b]pyridine-1,2-dicarboxylate (CAS 1269449-33-3) is a high-purity analytical reference standard with the molecular formula C15H17BrN2O4 and a molecular weight of 369.21 g/mol.

The molecular framework of 1-tert-Butyl 2-ethyl 4-bromo-1H-pyrrolo[2,3-b]pyridine-1,2-dicarboxylate (C15H17BrN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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.

CATO manufactures 1-tert-Butyl 2-ethyl 4-bromo-1H-pyrrolo[2,3-b]pyridine-1,2-dicarboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
