Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-1H-pyrrolo[2,3-b]pyridine.
2-Bromo-1H-pyrrolo[2,3-b]pyridine (CAS 1083181-25-2) is a high-purity analytical reference standard with the molecular formula C7H5BrN2 and a molecular weight of 197.03 g/mol.
Owing to a nitrile group, bromine substitution, an aromatic ring system, 2-Bromo-1H-pyrrolo[2,3-b]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2-Bromo-1H-pyrrolo[2,3-b]pyridine 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.
