Description
As a certified reference material (CRM), 4,5-Difluoro-1-(triisopropylsilyl)-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.
4,5-Difluoro-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (CAS 685513-89-7), molecular formula C16H24F2N2Si and molecular weight 310.46 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,5-Difluoro-1-(triisopropylsilyl)-1H-pyrrolo[2,3-b]pyridine (C16H24F2N2Si) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 310.46 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
