Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Formaldehyde-d2 (~20% in D2O).
Formaldehyde-d2 (~20% in D2O) (CAS 1664-98-8) is a high-purity analytical reference standard with the molecular formula CD2O and a molecular weight of 32.04 g/mol.
Owing to deuterium isotope labeling, a hydroxyl group, Formaldehyde-d2 (~20% in D2O) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 32.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
