Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4885-02-3 Dichloromethoxymethane Ether, dichloromethyl methyl Methane, dichloromethoxy- BRN 1900293 1,1-Dichlorodimethyl ether alpha,alpha-Dichloromethyl ether alpha,alpha-Dichloromethyl methyl ether 1,1-Dichloromethyl methyl ether EINECS 225-498-9 Methoxydichloromethane NSC 91480.

4885-02-3 Dichloromethoxymethane Ether, dichloromethyl methyl Methane, dichloromethoxy- BRN 1900293 1,1-Dichlorodimethyl ether alpha,alpha-Dichloromethyl ether alpha,alpha-Dichloromethyl methyl ether 1,1-Dichloromethyl methyl ether EINECS 225-498-9 Methoxydichloromethane NSC 91480 (CAS 4885-02-3) is a high-purity analytical reference standard with the molecular formula C2H4Cl2O and a molecular weight of 114.96 g/mol.

Based on its molecular formula C2H4Cl2O, 4885-02-3 Dichloromethoxymethane Ether, dichloromethyl methyl Methane, dichloromethoxy- BRN 1900293 1,1-Dichlorodimethyl ether alpha,alpha-Dichloromethyl ether alpha,alpha-Dichloromethyl methyl ether 1,1-Dichloromethyl methyl ether EINECS 225-498-9 Methoxydichloromethane NSC 91480 contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 114.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
