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 948-03-8 Methyl 1-hydroxy-2-naphthoate 2-Naphthalenecarboxylic acid, 1-hydroxy-, methyl ester EINECS 213-434-2.
CATO supplies 948-03-8 Methyl 1-hydroxy-2-naphthoate 2-Naphthalenecarboxylic acid, 1-hydroxy-, methyl ester EINECS 213-434-2 (CAS 948-03-8), a certified reference material (molecular formula C12H20O3, MW 212.29 g/mol) for analytical method development and quality control.
948-03-8 Methyl 1-hydroxy-2-naphthoate 2-Naphthalenecarboxylic acid, 1-hydroxy-, methyl ester EINECS 213-434-2 (C12H20O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
