Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Chloro-4,4-dimethylthiochroman-6-carbaldehyde 1,1-dioxide.
CATO supplies 8-Chloro-4,4-dimethylthiochroman-6-carbaldehyde 1,1-dioxide (CAS 1350761-72-6), a certified reference material (molecular formula C12H13ClO3S, MW 272.75 g/mol) for analytical method development and quality control.
8-Chloro-4,4-dimethylthiochroman-6-carbaldehyde 1,1-dioxide (C12H13ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
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 8-Chloro-4,4-dimethylthiochroman-6-carbaldehyde 1,1-dioxide 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.
