7-Methoxynaphthalene-1-sulfonyl chloride CAS 56875-61-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methoxynaphthalene-1-sulfonyl chloride.

CATO supplies 7-Methoxynaphthalene-1-sulfonyl chloride (CAS 56875-61-7), a certified reference material (molecular formula C11H9ClO3S, MW 256.71 g/mol) for analytical method development and quality control.

7-Methoxynaphthalene-1-sulfonyl chloride (C11H9ClO3S) 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.

As a certified reference material (CRM), 7-Methoxynaphthalene-1-sulfonyl chloride 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.
