4-(6-Hydroxy-4,4-dimethyl-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)benzonitrile CAS 1956340-42-3 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 4-(6-Hydroxy-4,4-dimethyl-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)benzonitrile.

4-(6-Hydroxy-4,4-dimethyl-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)benzonitrile (CAS 1956340-42-3), molecular formula C19H17NO2 and molecular weight 291.34 g/mol, is a CATO reference standard with documented purity and traceability.

4-(6-Hydroxy-4,4-dimethyl-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)benzonitrile (C19H17NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. 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.

As a certified reference material (CRM), 4-(6-Hydroxy-4,4-dimethyl-1-oxo-1,2,3,4-tetrahydronaphthalen-2-yl)benzonitrile 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.
