Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Methyl-6,7-dihydro-1,2-benzisoxazol-4(5H)-one 61834-40-0 6775AE C8H9NO2 (CAS 61834-40-0), a certified reference material (molecular formula C8H9NO2, MW 151.16 g/mol) for analytical method development and quality control.
3-Methyl-6,7-dihydro-1,2-benzisoxazol-4(5H)-one 61834-40-0 6775AE C8H9NO2 (C8H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 3-Methyl-6,7-dihydro-1,2-benzisoxazol-4(5H)-one 61834-40-0 6775AE C8H9NO2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
