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 Sodium 2-Keto-4(RS)-methyl-d3-pentanoate (CAS 93523-67-2), a certified reference material (molecular formula C6H6D3O3Na, MW 155.14 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Sodium 2-Keto-4(RS)-methyl-d3-pentanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Sodium 2-Keto-4(RS)-methyl-d3-pentanoate 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.
