Dichloromethane-D2 CAS 1665-00-5 chemical structure

Description

CATO supplies Dichloromethane-D2 (CAS 1665-00-5), a certified reference material (molecular formula CD2Cl2, MW 86.94 g/mol) for analytical method development and quality control.

The molecular framework of Dichloromethane-D2 (CD2Cl2) is characterized by deuterium isotope labeling, 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.

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.
