4-氯苯乙烯-d<SUB>7</SUB> CAS 285132-90-3 chemical structure

Description

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

4-氯苯乙烯-d<SUB>7</SUB> (CAS 285132-90-3) is a high-purity analytical reference standard with the molecular formula C8H6D7Cl and a molecular weight of 151.68 g/mol.

Owing to deuterium isotope labeling, chlorine substitution, an aromatic ring system, 4-氯苯乙烯-d<SUB>7</SUB> is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
