Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3-Dichloro-2-(methoxymethoxy)propane-d5 1189863-31-7 [2-Chloro-1-(chloromethyl)ethoxy]methoxymethane-d5.
1,3-Dichloro-2-(methoxymethoxy)propane-d5 1189863-31-7 [2-Chloro-1-(chloromethyl)ethoxy]methoxymethane-d5 (CAS 1189863-31-7), molecular formula C5H5D5Cl2O2 and molecular weight 178.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Dichloro-2-(methoxymethoxy)propane-d5 1189863-31-7 [2-Chloro-1-(chloromethyl)ethoxy]methoxymethane-d5 (C5H5D5Cl2O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 178.07 g/mol, it falls into the medium-molecular-weight range. 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.
