6,7-difluorobenzo[b]thiazolo[3,4-d][1,4]oxazine-1(4H)-thione CAS 119474-31-6

Description

CATO supplies 6,7-difluorobenzo[b]thiazolo[3,4-d][1,4]oxazine-1(4H)-thione (CAS 119474-31-6), a certified reference material (molecular formula C10H5F2NOS2, MW 257.28 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 6,7-difluorobenzo[b]thiazolo[3,4-d][1,4]oxazine-1(4H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 6,7-difluorobenzo[b]thiazolo[3,4-d][1,4]oxazine-1(4H)-thione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
