The occurrence of Dichloroacetaldehyde Hydrate Solution (Second Source), 1,000 mg/L, 1 ml is closely related to a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dichloroacetaldehyde Hydrate Solution (Second Source), 1,000 mg/L, 1 ml (CAS 79-02-7) is a high-purity analytical reference standard with the molecular formula C2H2Cl2O and a molecular weight of 112.94 g/mol.
The molecular framework of Dichloroacetaldehyde Hydrate Solution (Second Source), 1,000 mg/L, 1 ml (C2H2Cl2O) is characterized by 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.
