2-Keto-3-(methyl-d<SUB>3</SUB>)-butyric acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB> sodium salt CAS 1215605-14-3

Description

The occurrence of 2-Keto-3-(methyl-d<SUB>3</SUB>)-butyric acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB> sodium salt is closely related to deuterium isotope labeling, a carboxylic acid group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Keto-3-(methyl-d<SUB>3</SUB>)-butyric acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB> sodium salt (CAS 1215605-14-3), a certified reference material (molecular formula C[13C]4H4D3O3 Na, MW 105.08 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a carboxylic acid group, an ether linkage, 2-Keto-3-(methyl-d<SUB>3</SUB>)-butyric acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB> sodium salt is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 105.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 2-Keto-3-(methyl-d<SUB>3</SUB>)-butyric acid-1,2,3,4-<SUP>13</SUP>C<SUB>4</SUB> sodium salt 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.
