Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 53I7K68X7Z 672-89-9 Methyltriacetolactone 4-Methoxy-6-methyl-2H-pyran-2-one 2H-Pyran-2-one, 4-methoxy-6-methyl- 5-18-01-00110 (Beilstein Handbook Reference) BRN 0115970 EINECS 211-600-9 Methyltriacetolacton [German] NSC 139216 Methyltriacetolacton UNII-53I7K68X7Z (CAS 672-89-9), a certified reference material (molecular formula C7H8O3, MW 140.14 g/mol) for analytical method development and quality control.

53I7K68X7Z 672-89-9 Methyltriacetolactone 4-Methoxy-6-methyl-2H-pyran-2-one 2H-Pyran-2-one, 4-methoxy-6-methyl- 5-18-01-00110 (Beilstein Handbook Reference) BRN 0115970 EINECS 211-600-9 Methyltriacetolacton [German] NSC 139216 Methyltriacetolacton UNII-53I7K68X7Z (C7H8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
