252004-45-8 4-chloranyl-2,6-bis(fluoranyl)benzaldehyde 4-chloro-2,6-difluorobenzaldehyde A817702 CAS 252004-45-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 252004-45-8 4-chloranyl-2,6-bis(fluoranyl)benzaldehyde 4-chloro-2,6-difluorobenzaldehyde A817702.

CATO supplies 252004-45-8 4-chloranyl-2,6-bis(fluoranyl)benzaldehyde 4-chloro-2,6-difluorobenzaldehyde A817702 (CAS 252004-45-8), a certified reference material (molecular formula C7H9ClF2O, MW 182.60 g/mol) for analytical method development and quality control.

252004-45-8 4-chloranyl-2,6-bis(fluoranyl)benzaldehyde 4-chloro-2,6-difluorobenzaldehyde A817702 (C7H9ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
