Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-ethyl N'-5-amino-1-phenyl-1H-pyrazole-4-carbonylacetohydrazonate 99347-10-1 Ethyl N-[(5-amino-1-phenyl-1H-pyrazol-4-yl)carbonyl]ethanehydrazonoate.

(E)-ethyl N'-5-amino-1-phenyl-1H-pyrazole-4-carbonylacetohydrazonate 99347-10-1 Ethyl N-[(5-amino-1-phenyl-1H-pyrazol-4-yl)carbonyl]ethanehydrazonoate (CAS 99347-10-1), molecular formula C14H17N5O2 and molecular weight 287.32 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-ethyl N'-5-amino-1-phenyl-1H-pyrazole-4-carbonylacetohydrazonate 99347-10-1 Ethyl N-[(5-amino-1-phenyl-1H-pyrazol-4-yl)carbonyl]ethanehydrazonoate (C14H17N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
