Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including F414S3V8K6 589-57-1 Ethyl phosphorochloridite Diethyl chlorophosphite Phosphorochloridous acid, diethyl ester EINECS 209-652-2 UNII-F414S3V8K6.
CATO supplies F414S3V8K6 589-57-1 Ethyl phosphorochloridite Diethyl chlorophosphite Phosphorochloridous acid, diethyl ester EINECS 209-652-2 UNII-F414S3V8K6 (CAS 589-57-1), a certified reference material (molecular formula C4H10ClO2P, MW 156.55 g/mol) for analytical method development and quality control.
The molecular framework of F414S3V8K6 589-57-1 Ethyl phosphorochloridite Diethyl chlorophosphite Phosphorochloridous acid, diethyl ester EINECS 209-652-2 UNII-F414S3V8K6 (C4H10ClO2P) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
