Description

Compared with other compounds in its class, the molecular weight of 194.68 g/mol gives 2-(chloromethyl)-2,3-dihydrothieno[3,4-b][1,4]dioxine 857419-46-6 A10251 Thieno[3,4-b]-1,4-dioxin,2-(chloromethyl)-2,3-dihydro- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(chloromethyl)-2,3-dihydrothieno[3,4-b][1,4]dioxine 857419-46-6 A10251 Thieno[3,4-b]-1,4-dioxin,2-(chloromethyl)-2,3-dihydro- (CAS 857419-46-6), a certified reference material (molecular formula C7H11ClO2S, MW 194.68 g/mol) for analytical method development and quality control.

The molecular framework of 2-(chloromethyl)-2,3-dihydrothieno[3,4-b][1,4]dioxine 857419-46-6 A10251 Thieno[3,4-b]-1,4-dioxin,2-(chloromethyl)-2,3-dihydro- (C7H11ClO2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

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.
