Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1''-Terphenyl, 3',4',5',6'-tetraphenyl- 992-04-1 Benzene, hexaphenyl- Hexaphenylbenzene NSC-220313 NSC220313 m-Terphenyl,4',5',6'-tetraphenyl-.
CATO supplies 1,1''-Terphenyl, 3',4',5',6'-tetraphenyl- 992-04-1 Benzene, hexaphenyl- Hexaphenylbenzene NSC-220313 NSC220313 m-Terphenyl,4',5',6'-tetraphenyl- (CAS 992-04-1), a certified reference material (molecular formula C42H72, MW 577.02 g/mol) for analytical method development and quality control.
The molecular framework of 1,1''-Terphenyl, 3',4',5',6'-tetraphenyl- 992-04-1 Benzene, hexaphenyl- Hexaphenylbenzene NSC-220313 NSC220313 m-Terphenyl,4',5',6'-tetraphenyl- (C42H72) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
