2574-25-6 Phosphorochloridic acid, bis(1-methylethyl) ester (9CI) Phosphorochloridic acid, diisopropyl ester 4-01-00-01480 (Beilstein Handbook Reference) BRN 0471612 Diisopropyl chlorophosphate Diisopropyl phosphorochloridate Isopropyl phosphorochloridate (CAS 2574-25-6), molecular formula C6H14ClO3P and molecular weight 200.60 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2574-25-6 Phosphorochloridic acid, bis(1-methylethyl) ester (9CI) Phosphorochloridic acid, diisopropyl ester 4-01-00-01480 (Beilstein Handbook Reference) BRN 0471612 Diisopropyl chlorophosphate Diisopropyl phosphorochloridate Isopropyl phosphorochloridate (C6H14ClO3P) is characterized by a phosphonate group, 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.

As a certified reference material (CRM), 2574-25-6 Phosphorochloridic acid, bis(1-methylethyl) ester (9CI) Phosphorochloridic acid, diisopropyl ester 4-01-00-01480 (Beilstein Handbook Reference) BRN 0471612 Diisopropyl chlorophosphate Diisopropyl phosphorochloridate Isopropyl phosphorochloridate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
