Chemical Structure
Description
As a certified reference material (CRM), N-(7-chloro-2,3-dihydro-1,4-benzodioxin-6-yl)-4-fluorobenzamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies N-(7-chloro-2,3-dihydro-1,4-benzodioxin-6-yl)-4-fluorobenzamide (CAS 931621-75-9), a certified reference material (molecular formula C15H11ClFNO3, MW 307.70 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N-(7-chloro-2,3-dihydro-1,4-benzodioxin-6-yl)-4-fluorobenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
