Chemical Structure

氙-<SUP>128</SUP>Xe CAS 27818-78-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 氙-<SUP>128</SUP>Xe.

氙-<SUP>128</SUP>Xe (CAS 27818-78-6), molecular formula [128Xe] and molecular weight 127.90 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an inorganic composition, 氙-<SUP>128</SUP>Xe is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 127.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
