4-Chloro-3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridine CAS 869335-20-6

Description

4-Chloro-3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridine (CAS 869335-20-6) is a high-purity analytical reference standard with the molecular formula C14H10ClIN2O2S and a molecular weight of 432.66 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, 4-Chloro-3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-Chloro-3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridine 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.
