5-methylnaphthalene-1-carboxylic acid CAS 4527-60-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-methylnaphthalene-1-carboxylic acid.

CATO supplies 5-methylnaphthalene-1-carboxylic acid (CAS 4527-60-0), a certified reference material (molecular formula C21H15BrN2OS, MW 423.33 g/mol) for analytical method development and quality control.

5-methylnaphthalene-1-carboxylic acid (C21H15BrN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 5-methylnaphthalene-1-carboxylic acid 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.
