Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-4-Fluoro-1-Nitrobutane.
CATO supplies 1-Chloro-4-Fluoro-1-Nitrobutane (CAS 63732-17-2), a certified reference material (molecular formula C4H7ClFNO2, MW 155.56 g/mol) for analytical method development and quality control.
1-Chloro-4-Fluoro-1-Nitrobutane (C4H7ClFNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
