Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Chloro-4-((4-fluorobenzyl)thio)-2,3-dihydrobenzo[b][1,4]thiazepine.
CATO supplies 7-Chloro-4-((4-fluorobenzyl)thio)-2,3-dihydrobenzo[b][1,4]thiazepine (CAS 303987-75-9), a certified reference material (molecular formula C16H13ClFNS2, MW 337.86 g/mol) for analytical method development and quality control.
7-Chloro-4-((4-fluorobenzyl)thio)-2,3-dihydrobenzo[b][1,4]thiazepine (C16H13ClFNS2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
