N-methyl-N-(2-(3,4-dichloro­phenyl­)-4-hydroxy­butyl­)-benz­amide CAS 142001-90-9 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 N-methyl-N-(2-(3,4-dichloro­phenyl­)-4-hydroxy­butyl­)-benz­amide.

N-methyl-N-(2-(3,4-dichloro­phenyl­)-4-hydroxy­butyl­)-benz­amide (CAS 142001-90-9) is a high-purity analytical reference standard with the molecular formula C18H19Cl2NO2 and a molecular weight of 352.25 g/mol.

N-methyl-N-(2-(3,4-dichloro­phenyl­)-4-hydroxy­butyl­)-benz­amide (C18H19Cl2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), N-methyl-N-(2-(3,4-dichloro­phenyl­)-4-hydroxy­butyl­)-benz­amide 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.
