Description
Compared with other compounds in its class, the molecular weight of 210.62 g/mol gives Methyl 5-chloro-1H-pyrrolo[2,3-c]pyridine-7-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 5-chloro-1H-pyrrolo[2,3-c]pyridine-7-carboxylate (CAS 1660116-87-9), a certified reference material (molecular formula C9H7ClN2O2, MW 210.62 g/mol) for analytical method development and quality control.
Methyl 5-chloro-1H-pyrrolo[2,3-c]pyridine-7-carboxylate (C9H7ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 5-chloro-1H-pyrrolo[2,3-c]pyridine-7-carboxylate 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.
