Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethanone, 2,2,2-trichloro-1-(1-methyl-5-nitro-1h-pyrrol-2-yl)-.
Ethanone, 2,2,2-trichloro-1-(1-methyl-5-nitro-1h-pyrrol-2-yl)- (CAS 53391-42-7) is a high-purity analytical reference standard with the molecular formula C7H5Cl3N2O3 and a molecular weight of 271.49 g/mol.
Ethanone, 2,2,2-trichloro-1-(1-methyl-5-nitro-1h-pyrrol-2-yl)- (C7H5Cl3N2O3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 Ethanone, 2,2,2-trichloro-1-(1-methyl-5-nitro-1h-pyrrol-2-yl)- 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.
