Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3E)-1,1,1-trifluoro-5-[(2Z)-1,3,3-trimethyl-6-nitro-2,3-dihydro-1H-indol-2-ylidene]pent-3-en-2-one.
(3E)-1,1,1-trifluoro-5-[(2Z)-1,3,3-trimethyl-6-nitro-2,3-dihydro-1H-indol-2-ylidene]pent-3-en-2-one (CAS 379239-99-3), molecular formula C16H15F3N2O3 and molecular weight 340.30 g/mol, is a CATO reference standard with documented purity and traceability.
(3E)-1,1,1-trifluoro-5-[(2Z)-1,3,3-trimethyl-6-nitro-2,3-dihydro-1H-indol-2-ylidene]pent-3-en-2-one (C16H15F3N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (3E)-1,1,1-trifluoro-5-[(2Z)-1,3,3-trimethyl-6-nitro-2,3-dihydro-1H-indol-2-ylidene]pent-3-en-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
