Description
The occurrence of N'-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]propanoyl}-1H-pyrrole-2-carbohydrazide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N'-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]propanoyl}-1H-pyrrole-2-carbohydrazide (CAS 339099-50-2), molecular formula C20H13Cl2F6N5O2 and molecular weight 540.25 g/mol, is a CATO reference standard with documented purity and traceability.
N'-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]propanoyl}-1H-pyrrole-2-carbohydrazide (C20H13Cl2F6N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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), N'-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-4-{2-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]propanoyl}-1H-pyrrole-2-carbohydrazide 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.
