Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-bromo-4-chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 784150-42-1), molecular formula C7H13BrClN3 and molecular weight 254.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-bromo-4-chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (C7H13BrClN3) is characterized by a nitrile group, chlorine/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.
As a certified reference material (CRM), 6-bromo-4-chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine 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.
