Description

CATO supplies 90101-20-5 A843444 N-(4-methyl-2-pyridinyl)carbamic acid tert-butyl ester tert-butyl N-(4-methylpyridin-2-yl)carbamate (CAS 90101-20-5), a certified reference material (molecular formula C11H22N2O2, MW 214.30 g/mol) for analytical method development and quality control.

90101-20-5 A843444 N-(4-methyl-2-pyridinyl)carbamic acid tert-butyl ester tert-butyl N-(4-methylpyridin-2-yl)carbamate (C11H22N2O2) contains an amino-acid-derived structure, an amide 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.

As a certified reference material (CRM), 90101-20-5 A843444 N-(4-methyl-2-pyridinyl)carbamic acid tert-butyl ester tert-butyl N-(4-methylpyridin-2-yl)carbamate 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.
