Chemical Structure
Description
The occurrence of methyl 4-chloro-5-methylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies methyl 4-chloro-5-methylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (CAS 310442-40-1), a certified reference material (molecular formula C9H16ClN3O2, MW 233.70 g/mol) for analytical method development and quality control.
methyl 4-chloro-5-methylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (C9H16ClN3O2) contains an amide group, a carboxylic acid 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 4-chloro-5-methylpyrrolo[2,1-f][1,2,4]triazine-6-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.
