1,1,1-Trifluoroethyl-PEG4-Tos CAS 1872433-61-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1-Trifluoroethyl-PEG4-Tos.

1,1,1-Trifluoroethyl-PEG4-Tos (CAS 1872433-61-8), molecular formula C17H25F3O7S and molecular weight 430.44 g/mol, is a CATO reference standard with documented purity and traceability.

1,1,1-Trifluoroethyl-PEG4-Tos (C17H25F3O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.

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.
